How Many Kinds of OTF Knives Exist?

There are many types of out-the-front knives. Below, we discuss their specific differences from one another.

1. Manual Knives

Manual types are the most popular that you’ll typically see in stores. The blades have consistent control and have a fixed place.

Manual knives also have one small button and a track enclosed to their blades.

To take out the knife, you must apply some finger pressure to fight the friction. This will make the blade slide along the track and move out to the handle.

2. Automatic Knives

Automatic knives are actually still similar to OTF knives, except the blade also has a button structure and a spring mechanism to discharge it. These variants also do not have the finger pressure to control the friction.

For automatic knives, they can be further divided into two types of knives – a single action knife and a double action knife.

With a single-action OTF knife, you don’t need to manually open the blade because it has an instant opening mechanism. If you need to have the manual insertion, a double-action automatic OTF knife has a dual-action mechanism.

Blade Types for an OTF Knife

When looking for a blade for your OTF knife, you should pay attention to two core kinds of blades: Edge and Shape

Edge Types

Straight Blade/Fixed Blade

Fixed blade knives are usually sturdy, smooth, and very sharp. It can cut the target quickly, so hunters prefer using this type for outdoor activities.

Full-Serrated Edge Blade

For those who want to cut rough and solid materials, the full-serrated edge one is your perfect choice. The length of the blade is jagged to support sharp cuts.

Partially-Serrated Edge Blade

A partially-serrated edge blade is a combination of a full-serrated edge and straight blades. The jagged side is built near the handle. This means that you can cut different targets during your outdoor activities, as well as during your mundane activities.

Shape Types

Tanto Blade

With tanto out the front knives, they have many angles and combine two straight edges that create one sharp angle.

The blade is quite easy to recognize whether the edge is serrated or straight. This is because the blade has a very particular shape.

The tanto shape is strong because it’s angular and the spine stays steady until it catches an angle. It also has a razor-sharp point.

Drop Point Blade

The drop point blade is one of the most popular knives for hunters as the tip is shaped under a convex arc. The tip narrows down to a single point instead of having a blunt top.

The arc of the drop point lets it stay in one place. This is what makes the drop point blade a lot chunkier than other point types.

Spear Point Blade

Spearpoint blades are also called double-edged knives because you can use both sides of the dagger blade. Like any other double edge knife, it has its own useful knife features.

Normally, spear point blades have one straight edge on one side with a partially jagged edge on another side. This isn’t the case for double-edged variants.

Double-edged knives have two sides and the taper makes a fine point. A spear point knife is definitely an effective double edge knife because of this.

Facts About OTF Knives


Originally invented in the mid 18th century, OTF knives received a lot of praise because they’re versatile utility tools. Soldiers and military personnel adored these knives as they are light, compact, and can be used with one hand.

People could even use these knives as utensils, light-duty cutting tools, and in emergencies, as self-defense weapons. However, while the design seems intimidating and there are several legislations that restrict their circulation, the lethality of such knives is mediocre at best.

The point blade could pierce and slash but otherwise, most out-the-front knives are not meant to be used as fighting knives.


Out the front knives is basically an OTF switchblade that lets the wielders deploy the blade right out of the front. Because of that, these knives prove handy when you have to navigate confined spaces.

That being said, various experts consider these knives to be only good for light-duty use. Considering the delicate construction of out-the-front knives, rough handlings would cause vital components to fail and render the point blade inoperable.

So if you’re looking for hardcore survival tools, OTF knives might not be exactly what you need.

However, they can still be convenient items to pack for your next hunting session.

Single-Action vs. Double-Action

As mentioned, there are two kinds of OTF knives: Manual knives (single-action OTF) and Automatic knives (double-action OTF).

Overall, single-action OTF knives contain fewer parts than their double-action knife counterparts so the chance of failure is low. A

And you should also know that the average price of double action OTF knives is fairly high, a manual knife tends to be much cheaper than an automatic knife.

So if you have a tight budget and want reliability, then just go for a single-action OTF knife instead of a double-action knife. Though they’re one of the best OTF knives you can opt for, you’ll end up spending more if you go for the double-action ones.

But if you have money to spare, then double-action models or a double edge knife would be good choices. This is since the double-action mechanism offers more knife features and benefits.

The Legality of OTF Knives

Different places have different rules regarding the purchase and possession of OTF models. In some regions, it’s not that big of a deal to own them and people can buy one from stores with relative ease.

On the other hand, certain governments make it illegal to bring OTF knives into their country unless the knives are exclusively imported for military use. That’s why it’s a good idea to research the local regulations before attempting to buy these knives anywhere.

Due to the high acquisition costs, it’s truly a shame for you to spend a lot of money on them only to see the authority confiscate them later.

Material of the Knife Blades

Similar to other knives, there are numerous types of steel for OTF knives.  To get the most out of them, you need to ensure that it has the right material.

Below are some materials often used for OTF blades, as well as everything you have to know about their characteristics. Crosscheck them with your tastes and preferences.


Also known as S30V, this is widely considered to be among the highest quality steels used for OTF knives, and pocket knives in general. Most of the knives include a glass breaker and as a result, the costs of knives that employ CPM S30V could get pretty high.

Introduced to the knife market by Crucible, CPM S30V is famous for its ability to retain edge sharpness for an extended period of time, as well as its included glass breaker. The fine grain of the Crucible steel blade makes it an excellent material for a point blade.

CPM S30V is greatly favored by many reputable knife manufacturers such as Spyderco, Benchmade (which is most known for its signature glass breaker), Kershaw, and Gerber.

On the downside, it takes time and effort to re-sharpen a CPM S30V blade.


Originating from Japan, AUS-8 is made from high chromium components. It also has low carbon fiber and steel which offers compromises between hardness and corrosion resistance.

Generally speaking, AUS-8 has low edge retention and is unable to keep sharpness compared to other high-end steel on the market. That being said, people still think highly of AUS-8 and multiple commercial OTF knives use their Aichi steel for their blades.

AS for re-sharpening, you could get edge retention in an AUS-8 blade without much difficulty as the material is quite easy to use. Usually, knives that have AUS-8 are affordable as well.


Despite the fact that the D2 is decades old and there have been considerable developments in metallurgy, many modern-day OTF knives still use it.

Often considered as a semi-stainless steel, D2 provides a knife blade with a substantial amount of resistance against corrosion. The toughness of D2 steel results in competent cutting ability.

Compared to other types of steel, D2 blades retain edge sharpness well even though the re-sharpen process is quite tedious. To get a fine edge on a D2 blade, you have to be experienced at sharpening and have the proper tools.


Produced by Takefu Special Steel, VG-10 is another Japan-made blade material that you should keep an eye out for. Containing a considerable amount of chromium element in its composition, VG-10 has superb corrosion resistance.  

Moreover, the presence of vanadium guarantees that a Takefu steel blade can handle heavy usage without failure. With proper re-sharpening, the VG-10 could get razor sharp so it’s a good choice for people that want to deliver swift and clean cuts.  

The average out-the-front knife that uses VG-10 nowadays are also very affordable.


Made in China, 8Cr13MoV is a cheap steel used for mid-range knives to reduce acquisition costs. Although it’s far from a top-of-the-line blade material, 8Cr13MoV possesses good corrosion resistance and hardness.

In less than ideal operating conditions, 8Cr13MoV blades can handle rough handling and harsh chemicals with no trouble. The tradeoff is that blades made from Chinese steel quickly lose the sharpness of their edge and frequent re-sharpening is a must.

Nonetheless, you’re on a budget for your knife, an 8Cr13MoV out-the-front knife would allow you to save a lot of money.

Taking Care of OTF Knives

As time passes, foreign elements (dust, pollution, dirt, etc.) will accumulate on these knives and interfere with the operating mechanism. That’s why it’s important to give them periodic maintenance sessions to keep them in good shape.

Once your these knives seem to not work as smoothly as usual, then that’s a sign that it’s time to clean. While you could have the knives serviced by professionals, it’s not too hard to maintain them on your own either.

All you need are some rags, lubricants, and a screwdriver.

Here is a quick guide to how to disassemble and clean an out-the-front knife for beginners and knife enthusiasts:

Step 1: Discharge the Knife Blade

Before you can maintain your OTF knife, you have to disable the safety lock and discharge its blade first. If the spring-assisted knife is discharged properly, the trigger will eject and retract the blade. This will facilitate the cleaning process.

Simply point the knife at a flimsy material like cardboard or a phonebook to fire the knife blade. After that, the spring-assisted mechanism will be non-functional to allow you to safely access the knife’s interior components.

Make sure to hold the blade and shake it slightly to determine whether it’s loosened or not. Only move on to the next step if you’re certain there’s absolutely nothing out of the ordinary when you retract the blade. 

Step 2: Open the Knife

Grab the screwdriver and remove every screw present on the exterior of the knife. To avoid misplacing the screws when you reassemble the knife or retract the blade, leave them in their holes.

Gently lift up the knife handle then get the internal components out. These include the slider, the spring, and the blade. The slider, along with the spring-assisted mechanism will offer no trouble but you should still stay concentrated while removing the blade.

By discharging the knife earlier, the blade should be loose now but you still need to hold on to its rear hinge to remove it. Needless to say, pay attention and handle the blade carefully as it could inflict injuries.

Step 3: Clean the Internal Components

Use a cloth to get rid of any dust, gunk, and crumbs built up on the knife components. Considering the precise layout of the deployment mechanism, it’s strongly recommended that you choose a lint-free cloth to prevent leaving behind strands of fiber.

There is no need to rush. Take your time and give each component of the knife a good cleaning. Regarding the knife blade, make sure that you don’t scrub its edge too aggressively.

One mistake is enough to allow the blade to swiftly slice through the cloth and give you nasty cuts. It’s best to use moderate amounts of force and move your hands slowly.

If your knife has a glass breaker, then you should also be thorough with cleaning that component too.

Step 4: Throw in Some Lubricants

There are various types of lubricants but if you are looking for a solid product, then WD-40 is for you. If you have better choices, feel free to use them by all means.

However, remember to stay away from thick lubricants because they could restrict the movement of the blade and prevent the knife from firing as designed.

As WD-40 is a light lubricant, it would slip in every nook and cranny of your out-the-front knife without obstructing the operating mechanism in the process.

In any case, use an appropriate amount of lubricant because you definitely don’t want the components to get too slippery.

Step 5: Put Everything Back Together

Wipe off the excess lubricant using a cloth and proceed to reassemble the knife. In most cases, you just have to redo everything that you just did when you took the knife apart.

That being said, in the rare case that you are unable to put everything back together, take a good look at the included manufacturer guide. It’s highly likely that by following the instructions, you should be able to figure out how to get your knife back in one piece.

Otherwise, send your knife to someone that has better knowledge. Attempting to jam the components back into the handle is not a very good idea.  

Common Questions About OTF Knives

Is It True That OTF Knives Can Cause Injuries Through the Discharge of the Blade?

Because of the deployment mechanism, there’s a misconception that it’s possible to hurt someone by pressing them against them and discharging the blade.

Actually, the spring of most OTF knives is quite weak. Most of the time, the spring mechanism only propels the blade forward for ¼ of the way and inertia takes care of the rest.

That means the blade could barely make a scratch on human bodies once discharged at close range, let alone deliver lethal wounds.

So if you have to use your OTF knife as a weapon, which is a role it’s inherently not suited for, get the blade out as soon as possible.

Do OTF Knife Users Often Experience Shipping Issues?

When it comes to shipping, the local regulations are actually against the decisive factors. For instance, in the US, a lot of manufacturers state on their website that they can’t ship OTF knives to certain states.

The US federal law also forbids the transfer of OTF knives between individuals with the notable exception of law enforcement officers, as well as soldiers.

That being said, the federal law on OTF knives and switchblades, in general, does not apply to manufacturers and dealers. Therefore, you could technically order these knives from certain brands in the US if the state authority tolerates their presence.

Why Does the Blade of My OTF Knife Refuse to Be Discharged?

Once discharge failures occur in your out-the-front knife, it’s highly likely that the operating mechanism is going through some difficulty.

In case the blade does move out a bit but is unable to lock up, the solution is quite simple. Most of the time, you should be able to solve such failures by adding lubricants to smoothen the components.

The lubricants would also remove foreign elements that might obstruct the operation of the spring.  

On the other hand, if you see that the blade is stuck tight and you can’t move it at all, there must be something wrong with the components themselves. At this point, the sensible course of action is to send the knife for repair.

Must I Store My OTF Knife in the Open Position?

A lot of people claim that you must store switchblades, including OTF knives, in the open position to reduce spring fatigue. While it sounds realistic and practical, the truth is a bit different compared to theory.

In fact, you would have virtually no trouble storing your OTF knife in any position you want, closed or open. Most springs don’t fail unless you decide to push them to their limits.

That is why there is no need to store your out-the-front knife in the open position, especially if you don’t have space to spare. Storing them in the open position can raise a couple of issues regarding safety in the long run as well.

How Often Should I Sharpen the Blade of OTF Knives?

As with any other knife, it’s dangerous to cut with a dulled OTF knife so periodic sharpening is necessary. Generally speaking, the usage frequency would decide how often you need to re-sharpen the blade of your OTF knife.

You could wait until you see that the blade is unable to deliver clean cuts. However, it’s best to sharpen if you use the knife for daily use. You can also just do it at least once a month or so.

About sharpening tools, there are a lot of options available at your disposal. From whetstone to ceramic rods, just pick what suits your taste.

If you really don’t have much confidence, sharpening services are excellent alternatives. Just keep in mind that they’ll be an added expense as well.
