A knife comprising a pair of elongate handle members that, when fitted together, form a mounting means for pivotal movements of a sharpened blade. The blade has a terminus at one end and a circular aperture adjacent the other end. The blade is movable between extended and folded positions, with the handle members forming a means for grasping the knife when the blade is in its extended position as well as safely enclosing the blade when the knife is not in use and the blade has been moved to its folded position. A protrusion is located mounted on the internal surface adjacent one end of each handle member, with each of the protrusions being disposed on only one side of a longitudinal centerline extending along the internal surface of each handle member. The part of each protrusion remote from the centerline has an essentially semi-circular surface, with the protrusions being caused, when the handle members have been interfitted, to reside closely together to define a substantially circular component. The aperture of the blade is of a diameter to be closely received upon the protrusions when the protrusions have been disposed closely together. The handle members are movable apart for…
