ABSTRACT:
A foldable hand tool, such as a pocket folding knife, includes a knife blade and a handle for storing the knife blade, and a pivotally biased lock bar to secure the blade in extended position. The knife also includes a pair of non-slip ridges mechanically interlocked with the handle in a region of the handle proximate to the blade when the blade is in stored position. The ridges, which project outwardly from the handle, are contoured to permit suitable engagement by the fingertips of a user's hand, thereby reducing slippage when the blade is extended from the stored position. The handle is formed of two keyed sections firmly assembled together by cooperation of a lock bar biasing spring with coaxially aligned holes formed in the keyed regions of the handle sections.
