What are OTF knives, and are they legal?

OTF stands for out the front, and it refers to the mechanism a knife uses to deploy the blade. In simpler terms, the OTF knife is a type of switchblade where the blade itself comes out from the front. A significant difference compared to standard switchblades, which comes out to the side. OTF knives are also known as sliding knives.

The best OTF knife should be a powerful and versatile tool that can be used for self-defense, hunting, cutting, and anything else you can think of. Thanks to the blade deployment, the knife will be small, lightweight, and powerful.

Now you know that OTF knives are a type of automatic / switchblade, and you can deduce that the same rules and regulations apply to them. This means that OTF knives are usually legal across the world, and they are not considered as a weapon. They are a type of pocket knife.

In the United States, only nine states consider these knives illegal. In other states, they are completely legal and can be used and carried freely. So yes, you can carry your OTF knife and use it when needed.

Smith & Wesson M&P 1084315 Flat Dark Earth Spear – Cheap Single action OTF knife

Smith & Wesson by BTI Tools 1084315 Flat Dark Earth Spear

Smith & Wesson by BTI Tools 1084315 Flat Dark Earth Spear is probably the best OTF knife if you want to own something unique. The biggest difference compared to other models is the deployment mechanism, and it will be explained below.

Hybrid deployment mechanism

These mechanisms are scarce, and the chances are low that you will find another model with the same technology. The difference is in the retractable operating method. You deploy the blade as usual, but when you want to retract it, you will pull a piece of nylon.

The S&W OTF knife itself is handy and a desirable variation. It is better than the single-action mechanisms, but not so good as dual-action ones. That’s why it is called a hybrid mechanism.

AUS-8 stainless steel

AUS-8 stainless steel is a common material for most knives. It is sturdy, rust-resistant, and it can be used for all kinds of applications. The steel is reasonably lightweight, which makes it ideal for switchblades. Some of the most expensive units are made from this steel.

Spear blade

The blade has a spear point, and you know that we prefer this design. It makes the blade deadlier and more appealing to use. At the same time, it makes usage effortless, which isn’t the case with dull blade points. The point is extremely sharp.


  • Quality
  • AUS-8 stainless steel
  • Spear blade
  • Affordable


  • Deployment mechanism may be an issue for some.
  • Handle feels cheap

Schrade Viper 3, OTF, is a worthy alternative to all models mentioned above. We liked the sleek design and a nice blade. The knife feels solid and strong, but it is also very light. The mechanism is above average, and the price is very affordable.

Safety lock

You will want to hear about the safety mechanism. It is mounted on the back of the knife, and it is effortless to use. The mechanism is reliable, as it should be, and can be activated with a single hand, although you will need some time to get used to it.

Black design

There is no need to explain this but stunning. The design of this Schrade OTF knife is excellent. Both the blade and the handle are black, and the knife feels and looks like a weapon, despite the fact it is a small switchblade.

We hope to see this model in different colors soon. It will make it more versatile and probably add importance to it. At the moment, only the black version is available, and it may be the best choice for most of you.

Advanced sharpness

The blade is slightly different than the others we tested. It is perfectly sharp, and it will cut through anything. It is also made from durable steel and immune to rust and corrosion. Be careful while using the knife, and always read the manual before you start.

Maintenance is kept to the minimum standard for all stainless steel blades.

The mechanism is dual-action, and we believe you know what this means. Add this feature to the overall design, and you have an outstanding OTF knife that can be used anywhere for any purpose you have in mind. And yes, the mechanism is reliable and considered as one of the best on the market.

Aluminum handle

The handle itself is a masterpiece. It is made from a select type of aluminum that feels different than any other. It offers a decent level of grip, and it is super-strong. Precisely this is the reason why we can add that the knife is made for heavy-duty operations.

The handle incorporates a lever used to activate the mechanism. It feels very nice, and it is comfortable, although the level of grip is significantly lower. We would like to see rubber or silicone pads on it in the future.

We should add that the mechanism is a heavy-duty, and it has been tested adequately on each unit before delivery. We tested our model countless times, and there were no complications or issues.

Sturdy design

Another significant benefit of the knife is the design itself. It makes the knife strong, and it feels robust when used. This primarily refers to the mechanism which doesn’t make any sounds while carrying the knife. Also, the handle feels stronger than usual.

How to Choose the Best OTF Knife for You

Venom Tiger Z Tactical Combat Knife - Double Edge Tactical Knife - Military EDC ToolAll of us want the best OTF knife only because it will be easy to use, practical, and strong utility. To find and purchase the best unit, we need to consider many things. Let’s call those things factors to parameters, and now we can start listing them.

The material of the blade

The blade is the most critical part of any knife, and OTF models are no different. If the blade is inferior in quality, it is irrelevant which type of handle, additional features, or the price that the unit has. This refers to all knives.

The materials to look for are stainless steel or carbon steel. Any other mixture of metals is weaker and won’t provide excellent performances. This means that the blade will chip, break, and become dull within minutes.

Stainless steel is a cost-effective option. It is easy to get a unit with this metal, it can be very durable, and it will look nice. The maintenance is simple, as well. Carbon steel, on the other hand, is more expensive, stronger, and requires more maintenance. Be free to choose the type of metal you are comfortable with.

Deployment mechanism – Single action vs. Dual-action OTF Knives

Here we have two main types. First of all, the deployment mechanism refers to the system that will deploy the blade from a resting position. A button or lever controls it, and it will activate the blade when pressed.

You can choose between single action and double or dual action mechanisms. A single-action type will be able to deploy the blade only. You need to use manual force to place it back in the handle. A dual-action mechanism will deploy the blade and also retract it in the handle.

We prefer double action OTF knives. They are a bit more expensive, complex to make, prone to malfunction but more useful, easier to use, and safer as well. You risk cuts while retracting the blade manually!.

Example for single action OTF knife: UPKK single action knife

Example for double action OTF knife: Venom 3TR Assisted Combat Knife


For ordinary knives, the handle can be made from all sorts of materials. After all, it needs to be strong and lightweight. This is partially true with the OTF knives. Yes, a handle should be both of the just mentioned things, but there is a catch.

A handle will be under a lot of stress when using the knife. There are springs inside it, and there are a lot of vibrations. If the weak handle is present on the knife, it will get more vulnerable in the future.

Weak handles can affect the deployment mechanism and can prevent it from operating. They can also break and be unable to protect the user from the blade.

The best handle is made from aluminum. This is a durable metal that is very resistant to vibrations while maintaining the low weight of the knife.

Safety mechanism

A safety mechanism is entirely different than the deployment mechanism we mentioned earlier. In general, it is used as an addition to preventing the blade from accidental deployment, and it deserves your full attention.

If you accidentally open the blade, you can injure yourself due to strong springs present in the action mechanism. A safety mechanism will prevent that, and it is a mandatory feature for all beginners.

Glass breaker

You can find a model with or without this feature. We prefer a model with it because it comes without any drawbacks, yet the glass breaker is there when you need it. You can remove it if you want, but there is no need for that.

A good thing is a fact most knives of this kind include glass breakers. We can add that they are almost standard with the knives of this caliber.

Tip of the blade

For most of you, the tip of a blade is irrelevant when looking for a new knife. After all, it isn’t something that will significantly change the functionality of a knife. The case with OTF knives is the opposite, and here’s why.

The knife with OTF design will be used to stab an object or anything you want to cut while the action mechanism is deployed. If the tip of the blade is dull, it will fail to inflict the damage. That’s why we recommend you, models, with spear tip design. They are simply the most effective.


This is a rare accessory you won’t get with most of the knives available on the market. The reasons for that are obvious. The blade is located inside the handle, so it isn’t exposed. As such, you don’t need a sheath in most cases.

If you still want a sheath, keep in mind that it needs to be suitable for an Out the front knife with a closed blade. This is the natural position of the knife, and it should be carried only in this form.

Pocket clip

It is another little feature we like and probably you will as well. A pocket clip is essential, especially if you know that a sheath isn’t included in the package. It will help you transport the knife, and it will be within you at all times.



We were impressed with the quality, the mechanism (double action), and the attention to detail, and the affordable price of the Venom 3TR OTF knife. We believe most of you will be entirely happy with this choice and will use the knife for decades. If you are looking for cheaper alternatives, try  OTF knives from Kaiqing or KHW.
