ABSTRACT:
A hand tool, e.g., a knife, includes a handle with a pair of spaced cover pieces, at least one blade or other implement pivotally attached to the handle for movement with respect thereto between folded and extended positions, a locking lever for maintaining the blade in the extended position until manually released, and a beam spring urging the lever toward the locking position. The tool also includes a liner in the form of a flat, metal plate affixed to one of the cover pieces within a recess closely surrounding the periphery of the liner and having a depth substantially equal to the liner's thickness. The beam spring is an integral part of the liner, being formed by a slotted or cut-away area providing an elongated arm integrally connected at one end to a body portion and having an opposite, terminal end portion extending laterally to bear against the locking lever.
