The original LAWKS mechanism consists of a switch on the handle of the knife, connected to the liner lock. When pulled back, the liner lock can easily be pushed back to close the knife. But when the safety switch is pushed forward, it acts as an extra lock ensuring the linerlock can not be used to close the knife, making the folding knife a ...
Photo of Walker Linerlock knives with closeup of locking mechanism. Linerlock mechanisms are most commonly composed of titanium alloy or steel. [8] The linerlock's locking side liner is split from the top toward the bottom, similar to an automotive leaf spring (also called a lock bar) that butts up against the tang of the blade to prevent the blade from closing.

An assisted-opening knife is a type of folding knife which uses an internal mechanism to finish the opening of the blade once the user has partially opened it using a flipper or thumbstud attached to the blade. [1] When the knife is in the closed position, the blade is held in place by means of torsion springs and an additional blade lock ...
Most notably, Walker is known for the invention of the Walker Linerlock in 1981, which has since become the industry standard in folding knife mechanisms. [2] [5] What sets Walker's design apart is a long split in one of the liners which acts as a leaf-spring in the liner of the knife accompanied. This feature cuts down on mechanical stress.
A slipjoint knife is one of the most ubiquitous types of pocketknives.A slipjoint knife consists of a handle with one or more folding blades. These blades are held in position by a strong "backspring" which biases them towards the open and closed position (that is the spring tries to hold the blade closed until it has been pulled past a 90 degree arc from the handle, when the spring force ...
An officer’s tool (also known as an A-tool, rex tool, or lock puller) is a forcible entry device used by firefighters and other first responders. Officer’s tools are designed to completely remove cylindrical locks from doors without causing major structural damage, allowing for direct access to the internal locking mechanism.
It is intended for attaching a bayonet, which is typically a short-bladed multipurpose knife bayonet. The bayonet lug is the metal mount that either locks the bayonet onto the weapon or provides a base for the bayonet to rest against, so that when a bayonet cut or thrust is made, the bayonet does not move or slip backwards.
The Chubb detector lock is a variation of the lever lock which was designed to detect and prevent picking attempts. Lever locks can be drilled, but usually a template or stencil is required to mark the drilling point, as the lock mechanism is commonly mortised into the door and so it is harder to determine the point at which to drill.
