There are many different types of knives, and we’re not just talking about the regular old kitchen knife. One type of knife that is becoming popular to carry with you when you go out is an OTF knife. These knives allow for quick deployment in self-defense or as a regular pocketknife. They can also be used in tactical situations when speed and stealth are essential considerations for your safety. We will help you find the best OTF knife according to your budget.
What are OTF Knives? 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 switchblade where the blade comes out from the front – a significant difference compared to standard switchblades, which come out to the side (OTS). OTF knives are also known as sliding knives.
The John Wick franchise of films has popularized these knives even among non- knife folks worldwide. Here are the knives used in John wick films.
Now that you know OTF knives are a type of automatic knife/switchblade, you can deduce that the same rules and regulations apply to them. In the United States, only six states consider these knives completely illegal. Some have restrictions on the blade length as well.
You may also find some assisted opening OTF knives these days. These knives have a lesser legal restriction compared to their automatic counterparts.
Refer to the image taken from AKTI.org for more details on the legality of these knives.

In addition, it is coated with black DLC, a finish that is admired for its ability to improve surface durability, lower reflectivity, and boost resistance to corrosion.
The single-edged blade’s razor-sharp edge, piercing tip, drop point, and sharpening recess make it unbelievably adaptable to semi-tactical or daily applications.
The black handle is made using aluminum. It is smooth enough to hold in your hand, and slight contouring facilitates in-hand comfort. In addition, the restricted checkered pattern is known to prevent fingers from slithering on the blade.

It has a titanium pocket clip, meaning you can keep it in a pocket or by the belt.
Best Assisted Opening OTF Knives
Most OTF knives are automatic. Hence in some states, they are illegal or need to adhere to blade length restrictions. On the other hand, assisted opening OTFs are boon to people who like the out the front knife concept but can’t have an out the front auto, for whatever reason.
S&W and Schrade have produced spring-assisted OTF knives that are legal across the United States. Because of its spring-assisted mechanism, these are excellent choices for a budget OTF knife.
Smith & Wesson SWOTF9TB – Cheap Single Action OTF
If you are interested in an assisted opening version, Smith & Wesson SWOTF9TB knife is probably the best OTF knife for you. It is 8.77″ long and features a 3.6″ blade. You can get it with a straight edge, as well as a partially serrated edge. You can also opt for a tanto or a spear point alternative.
Assisted opening deployment single-action mechanism
The difference is in the retractable operating method. You deploy the blade, as usual, using a thumb-slide after unlocking safety. But when you want to retract it, you can use the blade release and pull the lever down. Again, make sure your fingers do not come in the way of the lever for faster blade deployment.
It is different from the single-action mechanisms employed by Microtech Halo VI. I prefer this blade retraction technique compared to the Halo VI technique.
AUS-8 stainless steel
AUS-8 stainless steel is a common material for most knives. It is sturdy, rust-resistant, and can be used for all kinds of applications. In addition, the steel is reasonably lightweight, which makes it ideal for OTF knives.
- Safety lock
- AUS-8 stainless steel
- Straight edge and partially serrated edge versions are available
- Available in Tanto and SPearpoint blades
- Single action OTF
- Handle feels cheap
Schrade Viper – Best Cheap Assisted Open OTF Knife
Schrade Viper is a worthy alternative to the S&W version, yet cheaper. We liked the sleek design and the blade. The knife feels solid, but it is also very light. The mechanism is above average, and the price is very affordable.
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.
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. However, at the moment, only the black version is available, and it may be the best choice for most of you.
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 AUS-8 durable steel and is 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.

In addition, the spear point and single edge contribute to excellent cutting ability. Despite this, the Kapsule does not appear to be an ideal non-threatening tool. Such is the design!
The notched thumb rest delivers a safe grip, while the glass-filled nylon handle adds to this grip with its distinct texture, notches, and contours. It is lightweight, ambidextrous, and comes with a blue PVD coating for a visual appeal. The pivot, a big lanyard hole, and a backspacer have this coating.
At the butt end, the deep-carry, removable, and single-position pocket clip facilitates a discreet, comfortable carry. Overall, this small but functional Kershaw knife delivers utility through a compact body. However, you can even use it for tactical purposes.

How to Choose the Right OTF Knife for You
To find and purchase the best unit, we need to consider many things. So let’s discuss those factors.
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 unit’s price. But, again, 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 performance. Unfortunately, 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 look nice. The maintenance is simple, as well. On the other hand, carbon steel is more expensive, stronger, and requires more care. Be free to choose the type of metal you are comfortable with.
Deployment mechanism – Single-action vs. Dual-action Knives
Here we have two main types. First, the deployment mechanism refers to the system that will deploy the blade from a resting position. A button or lever controls it, activating 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 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 functional, easier to use, and safer. However, you risk cuts while retracting the blade manually!.
Example for single action OTF knife: MicroTech Halo VI
Example for double action OTF knife: Benchmade Infidel
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.
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 handle is weak, 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.
A safety mechanism is entirely different than the deployment mechanism we mentioned earlier. However, 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 the strong springs present in the action mechanism. A safety mechanism will prevent that, and it is a mandatory feature for all beginners.
You can find a model with or without this feature. However, we prefer a model with the feature because it comes without any drawbacks, yet the glass breaker is there when you need it.
The good thing is that most knives of this kind include glass breakers.
Tip of the blade
OTF knives are mainly for tactical usage. If the blade’s tip is dull, it will fail to inflict damage. That’s why we recommend models, with a spear tip design. They are simply the most effective. Tanto blades are fine as well.
It is another little feature we like and probably you will as well. A pocket clip is essential for portability and safe carrying, especially if a sheath isn’t included in the package.
We were impressed with the quality, the double-action mechanism, and the affordable price of the Viper Tec Black Ghost Knife. However, if you are looking for a higher-end OTF knife, go for the Infidel or the Ultratech. Either of them is a top-notch choice.
