The liner lock is easily the most popular knife lock found in folding knives. It was developed in the late 19th century, but was improved in the early 80s by knife-maker Michael Walker and was quickly adopted by a number of mainstream knife makers.
The liner lock functions with one section of the liner angled inward toward the inside of the knife. From this position, the liner is only able to go back to its old position with manual force, therefore locking it in place.
The tail of the liner lock, which is closest to the blade, is cut to engage the bottom of the blade under the pivot. If the user wants to disengage the lock, they must manually move the liner to the side, away from the blade bottom.
The liner lock was a great advancement in knife lock technology and assisted in the evolution of the tactical knife and one-handed knife.
