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.

Abstract: A sheath which permits the user to adjust the degree of retentional engagement of the knife within the sheath. The sheath is provided with a simple, adjustable, latch mechanism engaging the knife to prevent their accidental disengagement. The latch mechanism is substantially received within the sheath.

Abstract: The present invention is a combination tool that includes a pair of retractable jaws capable of being moved into an exposed operating position by inertial force using a single hand. The tool includes a single compact unit with, on one end of the handles, pivoted jaws sliding into and out of the handles and, at the distal end of the handles, a selected group of pivotally attached tools that perform various functions. Each of these pivotally attached tools is housed within one of the handles when not in use.
