Abstract
Abstract A sheath knife handle includes an arm member offset from the main portion of the handle and attached to the handle by a flexible segment to permit arm member displacement by pressing with a finger. The arm member includes a latch component which upon inward arm member movement disengages a knife sheath to permit removal of the knife. The knife handle may be equipped with dual arm members to provide a double locking arrangement operable by a gripping action of the thumb and index finger. The arm member additionally defines a recess in which is received the upper edge of the knife sheath.
