Abstract
Abstract A pocket knife is disclosed herein having a body including a pair of side portions separated by a spacer so as to define a storage cavity for a knife blade. The blade is pivotally carried by its end from a selected end of the body between a stored position and an open or operative position. A releasable lock mechanism is operably carried on the body for retaining the blade in its open position. The blade is provided with a cutting edge along an underside and a cutting edge of shorter length is provided along the top side and a finger depression is formed on the blade adjacent to an enlarged portion for grasping by the thumb of the user for urging the blade from its closed position into its open or operative position. A clip is incorporated into the body for supporting the knife in a pocket, on a belt or the like.
