Knife locks are mechanisms that secure the blade in the open position, providing stability and safety during use. Different knife lock types offer varying degrees of strength, ease of use, and complexity. Here are some common knife lock types:
- Liner Lock:
- The liner lock is one of the most popular and widely used knife locks. It consists of a thin metal liner inside the handle that, when the knife is opened, moves into position to lock the blade in place. To disengage the lock, the user pushes the liner to the side, allowing the blade to be closed.
- Frame Lock:
- Similar to the liner lock, the frame lock uses a portion of the handle frame itself to lock the blade. When the knife is open, a section of the frame moves behind the blade, preventing it from closing. To unlock, the user pushes the frame aside.
- Lockback:
- The lockback, also known as the spine lock or mid-lock, is a mechanism that features a metal piece on the spine of the handle. It engages with a notch on the tang of the blade, securing it in the open position. To release the lock, the user pushes down on a lever at the rear of the handle.
- Axis Lock:
- The axis lock is a patented design commonly associated with Benchmade knives. It uses a small, spring-loaded bar that runs perpendicular to the blade. When the knife is opened, the bar engages with a notch in the blade, preventing it from closing. To release, the user pulls back on the axis lock.
- Compression Lock:
- The compression lock is found on some Spyderco knives. It involves a small piece of metal that wedges between the blade tang and the handle, securing the blade in place. To release the lock, the user pushes down on the lock, freeing the blade.
- Slipjoint:
- The slipjoint is a non-locking mechanism commonly found in traditional pocket knives. It relies on spring tension to hold the blade open and features a notch in the handle where the blade rests. The user manually holds the blade open while using it, and there is no locking mechanism.
- Button Lock:
- The button lock, also known as plunge lock or plunge button lock, uses a button typically located on the handle to release the blade. Pressing the button disengages the lock, allowing the blade to be closed. It is commonly found in automatic or assisted-opening knives.
- Ball Bearing Lock:
- The ball bearing lock is a variant of the axis lock and features a ball bearing that moves into a depression in the blade tang when the knife is open. This lock provides a smooth operation and is known for its strength and reliability.
- Ring Lock:
- The ring lock, often associated with the CRKT M16 series, involves a ring that the user can rotate to lock or unlock the blade. When the ring is in the locked position, it engages with the tang of the blade, preventing it from closing.
These are just a few examples of the many knife lock types available. Each has its advantages and considerations, and the choice often depends on user preferences, the intended use of the knife, and design aesthetics.
