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. [9]
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 ...
Within systems engineering, quality attributes are realized non-functional requirements used to evaluate the performance of a system. These are sometimes named architecture characteristics, or "ilities" after the suffix many of the words share. They are usually architecturally significant requirements that require architects' attention. [1]
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 magnetic keyed lock or magnetic-coded lock is a locking mechanism whereby the key utilizes magnets as part of the locking and unlocking mechanism. Magnetic-coded locks encompass knob locks, cylinder locks , lever locks , and deadbolt locks as well as applications in other security devices.
A gravity knife is a knife with a blade contained in its handle, which opens its blade through the force of gravity. [1] This mechanism of opening is fundamentally different from the switchblade, which extends its spring-propelled blade automatically upon the push of a button, switch, or fulcrum lever. [1]
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.
