ABSTRACT:
A locking, folding knife or tool comprising a handle with a groove dimensioned to receive a knife blade or other instrument that pivots about an integral pivot post between a closed position in the groove and an extended position. The pivot post fits into a hole in the blade of the knife which has two cutout portions along the periphery of the hole. The pivot post has an additional cutout portion. The handle carries a bolt for pushing a spring biased transfer bar toward the blade thereby disengaging a locking pin from one of the cutout portions of the blade and engaging the cutout portion of the pivot post so that the blade can pivot freely about the pivot post. The first cutout portion locks the blade in the extended position; the second cutout portion retains but does not lock the blade in the closed position. Additionally, a strut pivoting between the transfer bar and the handle can be included for added security in the locking of the blade. Contouring of the handle assures that the bolt operating thumb of the user is forward of the bolt and thus cannot operated the bolt without a conscious effort to replace the thumb rearward onto the bolt and pushing forward.
