What are the types of locks available for your Pocket Knives?

Many people talk about the blade and blade material, or even the handle; but the poor lock system lies forgotten in it all. Do not even think for once that the same lock system is used for all pocket knives. So, here goes. We want to educate you about all the lock systems that you may find in pocket knives. Here they are:


This lock system is also known as mid locks or spine locks and even back locks. The lock bar and scales of the blade are pinned together, which causes pivoting in the middle. You get upward pressure behind the pivot point because a bent spring is fastened further back in the handle. When closed, you get a dent for opening due to the factor that the lock bar is set on a ramp in the bottom of the tang.

As soon as the knife is opened, the blade is locked into position because the front portion of the lock bar sets into the matching square protrusions at the top of the blade’s tang. The lock bar needs to be lifted for the release of the blade. So, the lock keeps the blade closed until and unless the bar is pressed.

Liner Lock:

It has found a popular audience in the modern pocket knives. It is easy to use, assemble and light on the pockets. These may not be the best, but they sure are cost-effective. When the blade is opened, the design is such that it uses the blade liners to engage with the back of tang.

The modern upgrades include the addition of a stop pin and a detent ball. The stop pin is anchored to the scales for perfect alignment of the blade, when opened. Detent ball is present on the liner lock and holds the blade closed, which offers a snappy opening action to the blade.

Frame Lock:

The design is quite similar to that of the liner lock, but the knives are stronger and comparatively bit simpler. The frame is thicker and covers the whole handle. The lock bar springs inward upon opening and engages towards the rear end of the blade’s tang, which locks it into position. The detent ball plays an important part in keeping the blade closed and maintains the tension for a snappy opening. The stop pin is mounted above the pivot, which reduces wear and tear of the lock bar.

These are the major and most popular types of lock system in a pocket knife. But, the list does not stop here! There are so many more like the compression locks, button locks and collar lock to name some. If in doubt, speak to an expert at the store you choose for your pocket knife. They will be able to guide you and find you the best one available in the market!
