Abstract

A locking sheath and knife combination is provided that includes a spring biased member that partially extends out of the handle of the knife and interacts with a catch on the sheath for securing the knife to the sheath. When the user wants to extract the knife from the sheath, the spring biased member is squeezed as the handle is grabbed, which rotates the spring biased member to be substantially fully contained within the handle of the knife, and is secured there by the lock spring plate. When the knife is inserted back into the sheath, a protrusion on the sheath interacts with the lock spring plate to automatically allow the spring biased member to rotate out of the handle, thereby securing the knife to the sheath.
