Abstract
A folding knife comprises a lock configured to more securely hold the blade in an extended position than conventional locks of conventional knives. The folding knife includes a handle, a blade movable relative to the handle to an extended position, and the lock that retains the blade in the extended position. The blade includes a cutting edge, and a tang that has a cavity and that is attached to the handle and pivotable about a pivot axis. The cavity includes a central axis parallel or substantially parallel with the pivot axis and that is located a distance away from the pivot axis that is greater than the distance between the pivot axis and the end of the handle. The lock includes a pin moveable relative to the handle and insertable into the cavity to retain the blade in an extended position. The lock holds the blade more securely by contacting the blade a further distance away from the location where the blade is attached to the handle than the distance between the same two locations of a conventional folding knife.
