What is a Liner Lock Knife?

Because of the many uses for a knife, they were created to not only be useful but easy to carry around. After it was no longer socially acceptable or frankly, necessary to carry around a knife in a scabbard, a folding knife was developed. A folding knife is a style where the blade can be folded back into its handle. This design is meant to be both safe and portable. 

The first of these were made with a hole or indent in the knife blade so that a person could use their fingernail to pull the knife out. However, this proved to be cumbersome and dangerous as well. It meant that in order to open up the knife you would need to use two hands, and also that it was possible to be hurt by the knife as it opened and closed. It was also possible that the knife would not stay open or closed as needed. This is why the liner lock knife system was invented. It was invented so that the knife could be opened and closed with one hand. This made the knife a lot safer, and allowed the tradition of carrying folding knives to continue. 

A liner lock knife is a knife that folds back in on itself, but one that has a liner lock, which is a way of using the knife with only one hand. It creates a smooth action and allows the user to be able to open and close the knife with the same hand they hold the knife. These are created so that a knife can be carried around, and opened and closed with minimal problems. 

Liner lock knives were first known as electrician’s knives and have been around since the 19th century. The knife is built such that when the knife is open, it is held in place by a leaf spring which is also called a lock bar. The lock bar or leaf spring holds the bottom of the blade and prevents it from closing. When the user of the knife wants the blade to close, he or she has to press the lock bar towards the handle side of the knife. This will allow the knife to snap closed. When the knife is closed, the lock bar will rest right on the handle of the knife, and out of the way. 

In 1980, a knife maker by the name of Michael Walker took the original liner lock design and changed it slightly.  He was able to change the leaf spring very slightly, which made it lock the blade open instead of simply keeping it straight. The changes that Walker made to the electricians knives allow the blade to truly be opened and closed using only one hand.  In order to do this, Walker removed a back spring, as well as added a detent ball, which would hold the knife in the correct position. Both of these things were done so that the knife would be safer and easier to use. After Michael Walker developed this updated liner lock knife, many other knife making companies picked it up and began to use it. It is now one of the most popular forms of knives. 

Most knife manufacturers create liner lock knives out of steel or titanium. This prevents them from rusting and allows them to maintain their color and sharpness for the duration of their lives. Because this knife has moving parts, it is important to use high-quality materials to ensure the usability and functionality of all of the moving parts. 

The lock liner knife is designed to be a portable and functional knife that can be kept with you at all times for easy use. It is also designed to be a safe knife to have around the house or in with hunting and fishing equipment. You can keep it safe and secure when it is in the closed position, and you can snap it open in order to use it – knowing that it will stay securely open until you want to close it. Using a liner lock knife is one of the ways that you can always have your knife, but always have it safely.
