Abstract
A knife has an elongated body having a front end formed with a forwardly projecting trapezoidal-section tongue having a pair of side surfaces and a base surface bridging the side surfaces and a holder formed with a complementary trapezoidal-section slot having a pair of side surfaces extending parallel to and longitudinally slidable on the body side surfaces and a base surface bridging the holder side surfaces, extending parallel to the body base surface, spacedly confronting the body base surface, and forming therewith a blade seat. The tongue and groove have widths measured parallel to the base surfaces and transversely of the elongated body that decrease uniformly forward so that the side surfaces converge forward. A blade is gripped between the base surfaces and projecting forward from the body and holder.
