Discontinued Gerber defensive survival knife. Frisco Shiv designed by Blackie Collins. This knife is in great condition with a few flaws. The blade edge has no nicks that I could find. The mechanism that locks the blade into the sheath is there and works. One of the medallions in the handle is missing, there are unusual wear grooves in the butt of the handle and the sheath has a crack on the corner that does not affect function. All pictured.
