Abstract:

A folding knife comprising a handle transversely flanking a knife blade movable within a slot formed through the handle. A complementary fixed bushing and pivot hole on the handle and knife blade provide a positive lock for the extended knife blade, in conjunction with a spring-biased ball that is located within the bushing and which bears radially outward against the surfaces of the pivot hole. The knife blade is manually releasable from its extended position by application of manual pressure to the blade in a direction perpendicular to bushing axis. The spring-biased ball also acts in cooperation with a notch in the pivot hole to serve as a releasable detent for maintaining the knife blade in its folded position.
