ABSTRACT:
A folding knife designed to be easily opened with one hand and having a thumb-actuated opening lever to pivot the blade from closed to opened positions. The thumb-actuated lever in a first preferred embodiment has an opening lever driving a sector gear that engages a drive gear for opening the blade. The opening lever remains within the plan-view outline of the knife body at all times. In another disclosed embodiment, the opening lever drives a cam which, in turn, causes a second lever to pivot within the body of the knife. Gear teeth on this second lever engage and rotate a blade drive gear, causing the blade to pivot between closed and opened positions. The opening lever in still another disclosed embodiment includes a thumb-operated slider having a cam surface engaging a follower to pivot a blade opening lever.
