What is an OTF knife? : What does it stand for?

If you happen to come across a knife with the label ‘OTF,’ realize that this is an acronym for the word ‘out—the- front,’ which should inform you that this knife’s blade expands from the grip or handle.

Most people refer to it as a switchblade or automatic knife, which is right, due to its ability to pop the blade out instantly. This tool is categorized in terms of gravity (gravity knife), automatic switchblade (automatic switchblade), manual (manual sliding knife), and spring (spring-assisted).

The gravity knife depends on the force of gravity (hence the name) for it to open. For this reason, the parachutists carried it on their pockets to free themselves from the chute upon landing. For the automatic switchblades, they usually possess a button which, when pushed, releases the blade.

The spring-assisted knife is opened by the person using it with the help of a thumb stand contained in the blade, or a flipper and, the blade of the manual sliding one is obtained through sliding it out with a button, located along the grip length and is mainly used to cut equipment.

What is dual action OTF knife?

Today, these knives are available in three types which are:

  •         Single action: whereby the blade is usually closed by hand and to open it, spring-mechanism must be employed.
  •         Dual-action: for you to open and close the blade, you must employ spring mechanism for both. It is also referred to us double action.
  •         Manual action: Here, you do not use the spring mechanism, but instead use a sliding button if you want to either close or open the blade.

 

The History of OTF Knife

In the year 1860, the foremost gravity knife was developed, followed by the first spring assisted one in 1861. At this time, the two were used to hold something while opening a folding knife, which later (in the 1970s) resulted to the invention of a thumb-stud which was pushed with the thumb to open the blade easily, and later a wedge (this was a flat disk vertical to the blade spine, this differentiate it from the thumb-stud) whose function resembled that of a thumb-stud.

Instead of the use of a thumb-stud and a wedge, a hole was created in the blade for the user’s thumb tip, which led to the creation of a folding knife. People discovered automatic knives when they watched ‘gang movies’ though, in reality, the gangs and everyone else could not afford them (they were expensive), but in 1970, the Chinese invented cheap ones.

The US government discovered these tools as well as their use through the media; instead of military utilization, criminals also used them for murder, and this led to their ban in the region.

 

Are OTF knives illegal or not?

For daily use, a small blade serves the best, whereas for technical activities, it preferable to buy the one with a large blade. The handle should take care of your hands from blisters, and the knife should also be of the correct weight to use easily.

➡  The form of the blade

Cutting edges exist in both straight and serrated ones. If your task requires straight cuts or you want to buy a knife for hunting, go for one that has a straight cutting edge. If you need to cut materials made from leather, choose a serrated one. It should be sharp to ease your work, but at the same time safe in use

  Nature of the steel

Choose one made from stainless steel, which is free from rust. Different steel types also require different attention, choose one that will not give you a hard time in its maintenance, one that you can easily sharpen by yourself and which will not require frequent sharpening so that it can serve you well for long.
