Best Strongest OTF knife 2021

2

While many kinds of knives are available in the United States, an OTF knife or out-the-front knife is an essential pocketknife. In these knives, the blade slides parallel with the handle. Also known as a sliding knife, they open and close through a hole. OTF knives are designed to provide the shortest opening time, which exerts a notable amount of force on the knife’s frame and other parts.

These knives are best for self-protection, heavy-duty application, and outdoor purposes (in your tool-box). OTF knives are useful in an emergency as most of them have glass breakers. While buying the strongest OTF knife for yourself, consider the blade size, edge type (straight, full serrated, partially serrated), shape of the blade (tanto, drop point, clip point, spear point), and best steel properties.

The blade size will depend on the kind of job for which you’ll require the knife. Everyday tasks can easily be carried out using small blades. But for massive works, you must use a large-blade knife. Tanto has an angular shape formed by joining two straight edges. In drop point edge, the tip is lowered, creating a convex arc. A clip point edge forms a concave angle, which differentiates it from a drop point. The Spear point is a balanced grind with the tip positioned at the blade’s center.

The best steel properties include toughness, strength, and rust resistance. Other features of steel-blade include edge holding ability, wear resistance, cost, stain-resistant, and high-chromium content. This article is a description of the five best OTF knives for 2021.

A Complete Buying Guide For OTF Knives

There are many knives available in the United States. One is an OTF knife or an out-the-front knife. Also known as sliding knives, they have blade slides parallel with the handle. OTF opens and closes through a hole. What makes such knives different from others of their tribe is their shortest opening time. They are ideal for self-protection, heavy-duty application, and outdoor purposes. With several other features, this knife is excellent for your toolbox. This article is a full buying guide for OTF knives.

Where would you use an OTF knife?

It is vital to decide your purpose behind buying the OTF knife. You must pick the model that best suits your requirement. If you merely want to add the OTF to your knife-collection, there will be one kind of knife. Some people use a sliding knife at home for day-to-day activities. So, for them, another. In the case of those going to hunt regularly, the toolbox essentially needs an OTF knife to hunt and for safety purposes.

So, before buying, one must decide how the knife will be used- for protection, killing, safety purposes, or everyday life tasks. The next step is to know the functioning of an OTF knife.

How does an OTF knife work?

This knife has a switch that requires a trigger to open the blade. The spring device is activated by pushing a fulcrum lever or switch on the knife. These are single-handed knives and can be manually closed using a rod or cocking lever to compress the next opening’s spring device.

There are double-action OTF knives in which the opening action also recompresses the spring tool to assist in closing using the same button or switch used for opening.

Features of an OTF knife

The first step is to know what will be the use of the OTF knife for you. The two actions are single and double action. The opening mechanism is necessary to be understood. The other essential features of an OTF knife includes blade type, quality, spring mechanism, safety.

Blade Type

The two edges of an OTF knife are a single edge or double edge blade. A single edge blade has only one cutting edge. It is ideal for your usual cutting works. The best part about the single-edged blade is the safety feature. It means, while working in tight spaces, you do not unintentionally cut other objects or surfaces.

Another factor is that the tip of a single edge is mightier than a double edge blade. A double edge blade is useful for self-defense purposes because it has sharp edges on both sides. In any adverse situation, when you have no idea wherefrom the danger may appear, such an OTF knife is hugely beneficial.

Edge type

The edge types for an OTF knife are straight, partially serrated, and full serrated. Straight Edge blades are the set for cutlery and everyday use knives. A Straight Edge cuts cleanly and sharpens quickly and easily. Therefore, it is an ideal choice for hunting. Fully Serrated blades efficiently outperform Straight edges when cutting fibrous material, like a rope. It is a strong edge and often leaves a ragged cut.

Serrations typically stay sharp longer than a straight edge but are much more difficult to sharpen once dull. Partially Serrated blades have the advantages of both Straight and Serrated edges in one knife blade. A partially serrated edge is a good bargain when the blade will be used for everyday purposes.

Blade shape

The blade shapes for an OTF knife are Tanto, Drop point, Clip point, and Spear Point. Tanto blades have an angular shape because two straight edges are joined. It is powerful due to the spine keeping its full width until it comes close to the tip. A Drop Point is found on hunting blades. The tip is lowered via a convex arc that differentiates it from the clip point.

Clip Point is used on most bowie knives. It uses a concave or straight cutout toward the tip. Spear Point is symmetrical, with the tip located at the blade’s center. It is double-edged. So, the spear point shape acts as a powerful dagger.

Quality

While buying an OTF knife, consider the quality of its steel. Good quality steel can retain a sharp edge that can be useful in day-to-day activities. An OTF knife does not have a fixed blade. So, it is likely to twitch frequently. The blade of your knife is essential. But along with that, the durability and strength of its steel matters.

Good quality steel is rust-resistant stainless steel. They require frequent sharpening owing to their softness. The better-quality steel has higher chromium content and needs less maintenance. Best quality steel has the highest chromium content with Vanadium for sharpness and retention. They are more durable. Along with steel, the handle of your knife should also be considered.

Safety

The handle size and material play a crucial role while selecting the best OTF knife. It should have an adequate grip surface when used in outdoor conditions. The OTF knife’s handle should protect the blade and the spring from sand, dirt, and water to increase its longevity.

A perfect shape bolster of sufficient thickness is required for all folding knives as it prevents the hand from slipping forward and getting hurt. If you are using the OTF for self-defense, it is even more important to check the safety feature. Hold the knife to know if it fits your hand well and fulfills your purpose.

Spring Mechanism

The type of opening mechanism you want for your OTF knife depends on the purpose of using it. You can either buy a single action knife or a double action OTF knife. A switch, button, or lever method for opening the knife is excellent when it comes to triggering. You would essentially want the knife to open quickly with one hand.

For such a deployment, you may prefer a double-action knife opened with a thumb switch. Make sure to buy an OTF knife with a reliable locking mechanism that securely holds the blade in open and closed positions.

How to use an OTF knife?

Firstly, you need to open the OTF knife. After that, it works like other long back and folding knives. Whatever you involve in- be it hobbies, cutting tasks at work, camping, fishing, and hunting, OTF knives are perfect. However, the main benefit of an OTF knife is its ability to be opened with one hand. OTF lets you have a free hand to hold whatever you want to cut. You can open the blade whenever you need it.

Why should you carry an OTF knife?

The firm grip of the knife handle makes OTF knife different from others. As the blade deploys, the knife is ready to use. These knives are useful in complicated situations, tight workspaces, and self-defense uses. If you have reduced grip strength, it is ideal. The best part is the single-handed opening and closing system of OTF knives.

Conclusion

This complete OTF knife guide aims at making buying knives easier for you. It is quick to open and close using a trigger single-handedly. After you choose the purpose (daily use, hunting, safety), you can pick the blade type (single-edged or double-edged) and the edge types (Straight, Partially-Serrated, fully-Serrated). Tanto, Drop point, Clip point are the blade shapes available.

After that, the quality of the blade-steel (good, better, or best) and spring mechanism should be considered. Understand the functioning of an OTF knife and how it works. Finally, taking reference from this buying guide, select the best OTF for yourself.
