Abstract
A knife for personal use includes a frame of two substantially identical frame plates held in registering parallelism by a spacer pinned in position. The frame plates have generally circular openings therethrough in alignment on a transverse axis. The openings each depart from circularity by including one and preferably two extended pockets. A blade at one end having an identical opening and a pocket or pockets has such end disposed between the plates and pivotally held therein by a flanged, threaded sleeve passing through the openings and secured by a ring nut. The sleeve at the flange end has a cross slot to define sleeve pockets registering with the plate and blade pockets. A headed bolt extends reciprocably and yieldably through the sleeve and at one end has a cross bar adapted in one position to seat in the blade pockets, in at least one of the plate pockets and in the sleeve pockets. A spring urges the bolt into that one position, but the bolt can be displaced to shift the bolt cross bar out of the blade pocket or pockets.
