ABSTRACT:
A locking knife and sheath combination which provides for automatic locking of the knife when inserted to the sheath and which allows release of the knife from the sheath by a squeezing of the knife's handle. The handle is provided with a locking lever on each edge thereof which engages with receivers on the sheath. The locking levers are spring-biased outwardly such that insertion of the knife into the sheath causes automatic engagement of the locking levers with the receivers on the sheath. Simultaneous inward squeezing of both of the locking levers, occasioned by the user's grasping of the knife's handle, causes the knife to disengage from the sheath to allow removal of the knife therefrom.
