America's Trusted Source for Premium Automatic Knives

An automatic knife is a folding knife that opens its blade automatically when the user presses a button, lever or switch on the handle. Unlike a manual folding knife, which requires the blade to be opened by hand, an automatic knife uses a spring-powered mechanism for fast, convenient one-handed deployment.

The two most common types are side-opening automatic knives and OTF knives. A side-opening automatic knife swings the blade out from the side of the handle, while an out-the-front, or OTF, knife deploys the blade through an opening at the front of the handle. Some OTF knives use a double-action mechanism that both deploys and retracts the blade with the same switch.

Automatic knives are available in a wide range of sizes, blade styles and materials for everyday carry, collecting, outdoor tasks and professional use. Laws governing the purchase, possession and carry of automatic knives vary by location, so buyers should review all applicable state and local regulations.

An automatic knife uses a spring-powered mechanism to open the blade when the user presses a button, lever or switch on the handle. When the knife is closed, the blade is held securely inside the handle while the internal spring remains under tension. Activating the opener releases the locking mechanism, allowing the spring to move the blade rapidly into the open position. A lock then engages to help keep the blade securely open until the user intentionally closes or retracts it.

There are two main types of automatic knives. A side-opening automatic knife swings the blade outward from the side of the handle, similar to a traditional folding pocket knife. An out-the-front, or OTF, knife deploys the blade through an opening at the front of the handle. Double-action OTF knives use the same sliding switch to both deploy and retract the blade, while single-action OTF knives deploy automatically but usually require the blade to be manually reset.

Automatic knives differ from assisted-opening knives because the automatic mechanism is activated directly by a button or switch on the handle. Assisted-opening knives require the user to begin moving the blade before the spring assists with the rest of the opening motion.

Regular cleaning, light lubrication and proper storage can help an automatic knife operate smoothly. Owners should also follow the manufacturer’s instructions and review applicable state and local laws regarding automatic-knife ownership and carry.

The primary difference between an automatic knife and an assisted-opening knife is how the blade is deployed.

An automatic knife (also called a switchblade) uses a spring that fully opens the blade when a button, lever, or sliding thumb switch is activated. Once the safety mechanism is disengaged, pressing the release instantly deploys the blade without the user manually moving the blade.

An assisted-opening knife, by contrast, requires the user to begin opening the blade manually using a thumb stud, thumb hole, or flipper tab. After the blade is partially opened, an internal spring assists and completes the opening motion. The blade cannot deploy from the closed position without the user first applying pressure to the blade itself.

How an Automatic Knife Works

An automatic knife stores spring tension while closed. Pressing the activation button or sliding the thumb switch releases the spring, causing the blade to open instantly and lock securely into place. Depending on the design, automatic knives may be:

• Side-opening automatic knives, where the blade swings out like a traditional folding knife.
• OTF (Out-the-Front) automatic knives, where the blade travels straight out of the front of the handle. Double-action OTF knives also retract using the same thumb switch.

Automatic knives are valued for their rapid deployment, reliable one-handed operation, and consistent performance.

How an Assisted-Opening Knife Works

An assisted-opening knife contains a spring that helps finish opening the blade, but it does not activate until the user manually starts the opening motion. After the blade moves several degrees, the spring takes over and rapidly opens the blade until it locks into place.

Because the blade must first be manually moved, assisted-opening knives are mechanically different from automatic knives.

Which Knife Is Better?

Neither design is universally better—the right choice depends on how you plan to use the knife.

Choose an automatic knife if you want:

• Instant push-button deployment
• Fast one-handed operation
• Reliable performance for everyday carry or professional use
• Side-opening or OTF automatic designs

Choose an assisted-opening knife if you prefer:

• A manual opening motion with spring assistance
• A familiar folding knife design
• A balance between traditional manual folders and automatic knives
• A knife for general everyday cutting tasks

Are Automatic Knives and Assisted-Opening Knives Legal?

Knife laws vary by state and local jurisdiction. In many areas, automatic knives are regulated differently than assisted-opening knives, and ownership, carry, or sale may be subject to specific laws. Assisted-opening knives are often treated similarly to manual folding knives, but regulations can still differ depending on where you live.

Always check your local and state knife laws before purchasing or carrying either type of knife.

Bottom Line

An automatic knife opens completely at the push of a button or thumb slide using an internal spring, while an assisted-opening knife requires the user to manually begin opening the blade before the spring assists with the rest of the motion.

If your priority is the fastest possible deployment and convenient one-handed operation, an automatic knife is the better choice. If you prefer a knife that begins opening manually but finishes quickly with spring assistance, an assisted-opening knife is an excellent everyday carry option.

Yes. OTF (Out-the-Front) knives are a type of automatic knife. Unlike traditional folding automatic knives that swing open from the side, an OTF knife deploys its blade straight out of the front of the handle using an internal spring-powered mechanism.

Because the blade opens automatically when the user activates a thumb slide or button, OTF knives are classified as automatic knives under most state and federal knife definitions.

What Is an OTF Knife?

An OTF knife (Out-the-Front knife) is an automatic knife designed with a blade that travels directly forward through the front of the handle instead of pivoting outward like a conventional folding knife.

Most modern OTF knives use a sliding thumb switch positioned on the handle. Moving the switch forward deploys the blade, and depending on the design, moving the switch back may also retract it.

OTF knives are popular for their fast, one-handed operation, slim profile, and innovative engineering, making them a favorite among everyday carry (EDC) enthusiasts, outdoor users, first responders, military personnel, and collectors.

Types of OTF Automatic Knives

There are two primary types of OTF automatic knives:

Double-Action OTF Knives

Double-action OTF knives are the most common style available today. The same thumb slide both deploys and retracts the blade, allowing fast, convenient one-handed operation without manually resetting the knife.

Benefits include:

• Rapid blade deployment and retraction
• Easy one-handed operation
• Convenient everyday carry
• Quick access for work and utility tasks

Single-Action OTF Knives

Single-action OTF knives automatically deploy the blade but require the user to manually reset or recharge the internal spring before the knife can be deployed again.

These models are less common and are typically found in specialized professional, military, or collectible applications.

How Are OTF Knives Different from Side-Opening Automatic Knives?

Both OTF knives and side-opening automatic knives are automatic knives, but they use different deployment methods.

Both designs provide reliable automatic deployment, and the best choice depends on your preferred opening style, intended use, and personal preference.

Are OTF Knives Good for Everyday Carry?

Yes. Many people choose OTF automatic knives for everyday carry because they offer:

• Fast, one-handed deployment
• Slim, pocket-friendly designs
• Reliable cutting performance
• Secure locking mechanisms
• Easy access during work, outdoor activities, and daily tasks

Modern OTF knives are available in a wide range of sizes, blade shapes, handle materials, and premium blade steels, making it easy to find a model suited for everyday use.

Are OTF Knives Legal?

Because OTF knives are automatic knives, their legality depends on the laws where you live. Some states allow ownership and everyday carry with few restrictions, while others regulate or prohibit the sale, possession, or carry of automatic knives.

Always review your local and state knife laws before purchasing, carrying, or traveling with an OTF knife.

Bottom Line

Yes, OTF knives are automatic knives. They use a spring-powered mechanism to automatically deploy the blade, but instead of opening from the side like a traditional automatic folding knife, the blade travels straight out through the front of the handle.

If you're looking for fast one-handed deployment, compact everyday carry, and modern automatic knife technology, an OTF knife is one of the most popular and versatile options available.

The biggest difference between an OTF (Out-the-Front) knife and a folding automatic knife is how the blade opens.

An OTF knife deploys the blade straight out through the front of the handle using a thumb slide and an internal spring-powered mechanism. A folding automatic knife (also called a side-opening automatic knife) opens by swinging the blade out from the side of the handle after the user presses a button or activates a lever.

Both are automatic knives, meaning the blade opens automatically using a spring. However, their opening mechanisms, blade movement, handling characteristics, and overall design are different.

What Is an OTF Knife?

An OTF (Out-the-Front) automatic knife features a blade that travels directly through the front of the handle instead of pivoting outward. Most modern OTF knives use a double-action mechanism that deploys and retracts the blade using the same thumb slide.

OTF knives are known for:

• Lightning-fast deployment
• Quick one-handed opening and closing
• Slim, pocket-friendly designs
• Modern engineering and precision mechanics
• Excellent everyday carry performance

Available in a wide variety of blade styles, handle materials, and premium blade steels, OTF knives are popular with everyday carry (EDC) enthusiasts, first responders, outdoor users, military personnel, and collectors.

What Is a Folding Automatic Knife?

A folding automatic knife uses an internal spring to automatically swing the blade open from the side of the handle when a button or lever is pressed. After use, the blade is manually folded back into the handle.

Because they resemble traditional folding knives, many users appreciate their familiar ergonomics and simple operation.

Folding automatic knives are commonly available with:

• Drop point blades
• Tanto blades
• Clip point blades
• Spear point blades
• Partially serrated or plain edges

These knives are valued for their reliability, strength, and versatility across a wide range of everyday cutting tasks.

Which Knife Opens Faster?

Both OTF knives and folding automatic knives deploy extremely quickly.

Modern premium models from reputable manufacturers are engineered for smooth, dependable deployment with minimal effort. In everyday use, the speed difference between quality OTF and folding automatic knives is generally negligible. Choosing between them is more about preferred opening style, ergonomics, and intended use than raw deployment speed.

Which Is Better for Everyday Carry?

Both designs make excellent everyday carry knives.

An OTF knife may be the better choice if you want:

• Straight-out blade deployment
• One-handed opening and closing
• A slim, modern design
• Quick access in confined spaces

A folding automatic knife may be the better choice if you prefer:

• Traditional folding knife ergonomics
• A familiar pocket knife feel
• Simple maintenance
• Strong blade lockup for everyday utility

Are Both Considered Automatic Knives?

Yes. Both OTF knives and folding automatic knives are classified as automatic knives because they use a spring-powered mechanism to deploy the blade automatically after the activation control is engaged.

The only difference is the direction the blade travels:

• OTF knives extend straight out the front.
• Folding automatic knives pivot open from the side.

Are OTF and Folding Automatic Knives Legal?

Knife laws vary by state and local jurisdiction. Because both designs are automatic knives, ownership, carry, and sale may be regulated differently depending on where you live.

Always review your local and state knife laws before purchasing or carrying any automatic knife.

Bottom Line

OTF knives and folding automatic knives both offer fast, one-handed automatic deployment, but they achieve it in different ways. An OTF knife sends the blade straight out of the front of the handle using a thumb slide, while a folding automatic knife swings the blade open from the side with the push of a button or lever.

If you prefer modern engineering, straight-line blade deployment, and automatic retraction, an OTF knife is an excellent choice. If you like the familiar feel of a traditional pocket knife combined with the convenience of push-button automatic opening, a folding automatic knife is likely the better fit.

No matter which style you choose, both provide reliable performance, convenient one-handed operation, and are available in a wide range of blade shapes, sizes, steels, and handle materials to suit everyday carry, outdoor use, work, and collecting.

A double-action OTF (Out-the-Front) knife is an automatic knife that uses a single thumb slide to both deploy and retract the blade. Unlike a single-action OTF knife, which requires the blade to be manually reset after opening, a double-action OTF knife performs both actions automatically through the same spring-powered mechanism.

Double-action OTF knives are among the most popular automatic knives for everyday carry (EDC), work, outdoor activities, professional use, and collecting because they offer fast, convenient one-handed operation and a compact, pocket-friendly design.

How Does a Double-Action OTF Knife Work?

A double-action OTF knife contains an internal spring and track system inside the handle. Moving the thumb slide forward causes the blade to extend straight out through the front of the handle until it locks securely into place. Pulling the thumb slide back automatically retracts the blade into the handle.

Because both deployment and retraction are controlled by the same thumb slide, the knife can be opened and closed quickly without manually touching the blade.

Double-Action OTF Knife Features

Most double-action OTF knives include features such as:

• Automatic blade deployment and retraction
• One-handed operation
• Straight-out blade movement
• Secure locking mechanism when open
• Slim, lightweight handle design
• Pocket clip for convenient everyday carry
• Available in multiple blade shapes and premium blade steels

Many models also include a glass breaker, ambidextrous pocket clip, textured handle, or corrosion-resistant finishes for added functionality.

Double-Action vs. Single-Action OTF Knives

Although both are automatic knives, there are important differences between double-action and single-action OTF knives.

Key advantages include:

• Fast blade deployment and retraction
• Easy one-handed operation
• Compact profile for comfortable pocket carry
• Minimal blade exposure when opening or closing
• Consistent, reliable performance
• Wide variety of blade styles and handle options

These characteristics make double-action OTF knives well suited for everyday cutting tasks, outdoor recreation, utility work, emergency preparedness, and collecting.

Are Double-Action OTF Knives Good for Everyday Carry?

Yes. Double-action OTF knives are widely considered one of the best automatic knife styles for everyday carry.

Their slim handles fit comfortably in a pocket, while the quick thumb-slide operation allows users to open and close the knife efficiently using one hand. Modern designs are available in compact, mid-size, and full-size configurations with blade styles including drop point, tanto, clip point, spear point, bayonet, and double edge.

Are Double-Action OTF Knives Automatic Knives?

Yes. A double-action OTF knife is a type of automatic knife because the blade is deployed by an internal spring-powered mechanism when the thumb slide is activated. The defining feature of a double-action OTF knife is that the same control also retracts the blade automatically.

Are Double-Action OTF Knives Legal?

Knife laws vary by state and local jurisdiction. Because double-action OTF knives are automatic knives, ownership, carry, and sale may be regulated differently depending on where you live.

Always check your local and state knife laws before purchasing or carrying any automatic knife.

Bottom Line

A double-action OTF knife is an automatic knife that both deploys and retracts its blade using a single thumb slide. Its fast one-handed operation, compact design, and convenient automatic retraction make it one of the most popular choices for everyday carry, outdoor use, work, and collecting.

Whether you're looking for a premium American-made model or an affordable everyday carry option, a double-action OTF knife offers the speed, convenience, and reliability that have made this automatic knife design a favorite among knife enthusiasts.

A side-opening automatic knife is an automatic folding knife that opens when the user presses a button or activates a lever, causing an internal spring to swing the blade out from the side of the handle. Unlike an OTF (Out-the-Front) knife, which deploys the blade straight out through the front of the handle, a side-opening automatic knife pivots open like a traditional folding pocket knife.

Because the blade opens automatically with the push of a button or lever, side-opening automatic knives are commonly referred to as automatic knives or switchblades.

How Does a Side-Opening Automatic Knife Work?

A side-opening automatic knife stores spring tension while the blade is closed. When the safety is disengaged and the activation button or lever is pressed, the spring releases, rapidly rotating the blade into the open position. Once fully open, the blade locks securely in place for safe use.

After use, the blade is manually folded back into the handle until it locks in the closed position, ready for the next deployment.

This simple and reliable mechanism has made side-opening automatic knives one of the most popular automatic knife designs for everyday carry and professional use.

Features of Side-Opening Automatic Knives

Most side-opening automatic knives include:

• Push-button or lever activation
• Fast automatic blade deployment
• One-handed operation
• Manual blade closing
• Secure blade lock when open
• Built-in safety to help prevent accidental deployment
• Pocket clip for convenient everyday carry

Many premium models also feature precision-machined handles, premium blade steels, textured grip surfaces, and corrosion-resistant finishes for long-lasting performance.

Are Side-Opening Automatic Knives Good for Everyday Carry?

Yes. Side-opening automatic knives are widely used for everyday carry because they combine the familiar feel of a traditional folding pocket knife with the convenience of automatic deployment.

They are well suited for opening boxes, cutting rope, preparing camping gear, outdoor recreation, general utility work, and everyday cutting tasks. Their compact size, secure locking mechanisms, and one-handed operation make them practical for daily use.

Are Side-Opening Automatic Knives Legal?

Knife laws vary by state and local jurisdiction. Because side-opening automatic knives are automatic knives, ownership, carry, and sale may be regulated depending on where you live.

Always review your local and state knife laws before purchasing or carrying any automatic knife.

Bottom Line

A side-opening automatic knife is a spring-powered folding knife that automatically pivots its blade open from the side of the handle when a button or lever is activated. It offers fast one-handed deployment while maintaining the familiar design and ergonomics of a traditional folding pocket knife.

Whether you're looking for an everyday carry knife, a dependable work tool, or a collectible automatic knife, side-opening automatic knives provide a proven combination of speed, reliability, convenience, and precision that has made them a favorite among knife enthusiasts for decades.

The best automatic knife for everyday carry (EDC) is one that combines reliable deployment, a practical blade shape, durable blade steel, comfortable ergonomics, and a size that's easy to carry every day. While there is no single "best" automatic knife for everyone, the ideal choice depends on how you plan to use it and your personal preferences.

Many everyday carry enthusiasts choose either an OTF (Out-the-Front) automatic knife or a side-opening automatic folding knife because both offer fast one-handed deployment and dependable performance.

What Makes a Great Everyday Carry Automatic Knife?

When choosing an automatic knife for daily use, consider these key features:

Reliable Automatic Action

A quality automatic knife should deploy smoothly and lock securely every time. Precision-engineered springs and locking mechanisms help ensure consistent performance whether you're using the knife at work, outdoors, or around the house.

Practical Blade Length

For most users, a blade between 3 and 3.5 inches provides an excellent balance of cutting performance, portability, and control. Compact automatic knives with blades under 3 inches are also popular where a smaller everyday carry knife is preferred.

Secure Locking Mechanism

A dependable locking system keeps the blade securely open during use. Common lock types include button locks, plunge locks, and internal OTF locking systems designed for strength and reliability.

Pocket-Friendly Design

A deep-carry or low-profile pocket clip, lightweight construction, and slim handle make an automatic knife more comfortable to carry throughout the day.

OTF Knife or Folding Automatic Knife for EDC?

Both styles are excellent choices for everyday carry.

OTF Automatic Knives

An OTF knife may be the better option if you want:

• Straight-out blade deployment
• One-handed opening and closing
• Slim, compact carry
• Fast access in confined spaces

Double-action OTF knives are especially popular because the same thumb slide both deploys and retracts the blade.

Folding Automatic Knives

Choosing the Right Blade Shape

The best blade shape depends on how you'll use the knife.

• Drop Point – The most versatile choice for everyday cutting, utility work, and outdoor tasks.
• Tanto – Strong tip designed for piercing and demanding applications.
• Clip Point – Excellent control with a fine tip for detailed cutting.
• Sheepsfoot – Great for controlled slicing while reducing the chance of accidental punctures.

• Will you carry the knife every day or only occasionally?
• Do you prefer an OTF or side-opening design?
• Which blade shape best fits your cutting tasks?
• Is lightweight carry a priority?
• Do you want premium blade steel for maximum edge retention or an easy-to-maintain stainless steel?

Answering these questions will help narrow your options and ensure you choose a knife that fits your needs.

Bottom Line

The best automatic knife for everyday carry is one that matches your daily tasks, feels comfortable in your hand, and delivers reliable automatic deployment every time. For most users, a quality automatic knife with a 3- to 3.5-inch blade, premium stainless steel, secure locking mechanism, and ergonomic handle offers the ideal combination of performance and portability.

Whether you choose a double-action OTF knife for its fast deployment and compact design or a side-opening automatic knife for its traditional feel and push-button simplicity, investing in a well-built automatic knife ensures dependable performance for everyday carry, work, outdoor adventures, and general utility.

The best blade steel for an automatic knife depends on how you plan to use the knife. Some steels are designed to maximize edge retention, while others prioritize toughness, corrosion resistance, or ease of sharpening.

For most users, premium stainless steels such as Böhler M390, M390MK, and CPM S30V offer the best overall combination of cutting performance, durability, corrosion resistance, and long-term value. However, high-quality steels like D2, 154CM, 440C, and 440A remain excellent choices for everyday carry, work, and outdoor use.

What Makes a Good Blade Steel?

When comparing blade steels for automatic knives, consider these five characteristics:

• Edge Retention – How long the blade stays sharp.
• Corrosion Resistance – How well the steel resists rust and staining.
• Toughness – The blade's ability to resist chipping or breaking under stress.
• Ease of Sharpening – How quickly the blade can be restored to a sharp edge.
• Wear Resistance – How well the steel withstands long-term use and abrasion.

No blade steel is perfect in every category, so the best choice depends on your priorities.

• Tight manufacturing tolerances
• Proper maintenance

A well-designed automatic knife with a properly heat-treated mid-range steel can often outperform a poorly manufactured knife made from a more expensive steel.

Bottom Line

The best blade steel for an automatic knife depends on your intended use and budget. Premium steels such as Böhler M390, M390MK, and CPM S30V deliver exceptional edge retention, corrosion resistance, and long-term performance for demanding users. For outstanding value, D2, 154CM, 440C, and 440A continue to be trusted choices for everyday carry, work, and outdoor use.

By selecting the right combination of blade steel, knife design, and intended purpose, you can choose an automatic knife that provides years of dependable cutting performance.

Yes, automatic knives are legal in many parts of the United States, but the laws vary by state, local jurisdiction, and how the knife is owned, carried, sold, or transported. Because regulations differ across the country, there is no single answer that applies everywhere.

Automatic knives—also known as switchblades, OTF (Out-the-Front) knives, and side-opening automatic knives—are legal for civilian ownership in most states, although some states or local jurisdictions impose restrictions on blade length, concealed carry, public carry, or specific locations where knives may be prohibited.

Do Automatic Knife Laws Vary by State?

Yes. Every state has its own knife laws, and some cities or counties may also have additional regulations.

Depending on where you live, laws may address:

• Ownership of automatic knives
• Carrying an automatic knife openly or concealed
• Blade length restrictions
• Age requirements for purchase
• Restrictions in schools, government buildings, airports, and other prohibited locations
• Transportation across state lines

Because laws can change through new legislation or court decisions, it's important to verify the current regulations before purchasing or carrying an automatic knife.

What Does Federal Law Say?

Federal law does not create one nationwide rule for owning or carrying automatic knives inside your state. Instead, the Federal Switchblade Act primarily regulates certain aspects of interstate commerce, importation, and mailing, while state and local laws generally determine whether automatic knives may be owned or carried where you live.

How Can I Check My State's Automatic Knife Laws?

Before purchasing or carrying an automatic knife, you should review the laws that apply in your state and local area.

To make this easier, Tactical Sporting Goods provides a state-by-state automatic knife law guide that can help you research current regulations before you buy.

Why It's Important to Know Your Local Knife Laws

Understanding your state's knife laws helps ensure you:

• Purchase a knife that is legal where you live
• Carry your knife responsibly
• Avoid unintended legal issues while traveling
• Stay informed about changes to state and local regulations

Because knife laws continue to evolve in many states, checking the current rules before buying or carrying an automatic knife is always the best practice.

Bottom Line

Automatic knives are legal in many U.S. states, but the rules vary depending on where you live. Ownership, carry, blade length, and transportation laws are determined by state and local regulations, so it's important to verify the laws that apply to your location before making a purchase or carrying an automatic knife.

At Southern Sporting Goods, we believe that quality matters more than quantity. While thousands of automatic knives are available online, not every product meets the standards we expect for performance, reliability, craftsmanship, and long-term value.

Instead of listing every automatic knife we can find, we carefully evaluate the brands and models we offer. Our goal is to provide customers with a curated selection of automatic knives from manufacturers that have earned a reputation for quality, dependable operation, and consistent manufacturing standards.

Why We Carefully Select the Automatic Knives We Sell

Not all automatic knives are made to the same standards. Some low-cost models may use inferior materials, inconsistent heat treatment, poor machining, or unreliable opening mechanisms. These issues can affect performance, durability, and overall customer satisfaction.

Our team researches and evaluates the products we carry by considering factors such as:

• Overall build quality
• Reliability of the automatic opening mechanism
• Blade steel and heat treatment
• Handle materials and construction
• Locking strength and safety features
• Manufacturer reputation
• Long-term value for our customers

If a product or brand doesn't meet our expectations, we simply choose not to offer it—even if it's widely available elsewhere.

A Curated Selection You Can Shop with Confidence

Our philosophy is simple: we'd rather offer a carefully selected collection of automatic knives that we believe in than overwhelm customers with products we wouldn't confidently recommend.

Whether you're shopping for an OTF knife, a side-opening automatic knife, an Italian switchblade, or an everyday carry automatic knife, you can shop knowing that every product has been chosen with quality, reliability, and customer satisfaction in mind.

We're Always Expanding Our Selection

Although we don't carry every automatic knife brand on the market, we're continually adding new products from manufacturers that meet our standards. As trusted brands introduce new models and innovative designs, we regularly expand our inventory to give customers more high-quality options.

Our goal is to offer one of the best selections of dependable automatic knives while maintaining the high standards our customers expect.

Our Commitment to You

We know buying an automatic knife online can be challenging, especially with so many brands and price points available. That's why we use our industry knowledge and experience to help take the guesswork out of the buying process.

By carefully selecting the products we sell, we strive to provide a safer, more confident shopping experience—helping you choose an automatic knife that delivers the quality, performance, and value you deserve.

Bottom Line

We don't measure our selection by the number of products we list—we measure it by the quality of the products we stand behind. While there are countless automatic knives for sale across the internet, we intentionally focus on brands and models that meet our standards for craftsmanship, reliability, and performance, so you can shop with confidence and enjoy a better ownership experience.
