ABSTRACT:
A folding knife is described which may be disassembled without the use of tools for the purpose of cleaning the interior, changing blades or the like. The knife has a pair of side plates each having a slot of nonuniform width near each end that align with corresponding slots in the facing plate. Annularly grooved pins fit in each aligned set of slots. A back spring is positioned between the side plates, and a pivot therethrough engages a cooperative pair of holes in the side plates. One grooved pin passes through a circular opening in the tang of a blade, the pin being the pivot for the blade. A second grooved pin passes through a circular opening in a locking cam unit, the pin being the pivot for the cam. When rotated in one direction the cam unit locks the grooved pins in the slots and tensions the back spring against the blade tang. Rotation in the opposite direction unlocks the pins, removes the spring force, and thereby permits the side plates to be moved apart and disengages all parts for cleaning or replacement.
