I have a knife made by my father on Guadalcanal. I don't remember what the steel blade used to be, but the laminated handle was made of discs of plexiglass, aluminum sheet metal, and brass sheet metal taken from a Japanese Zero fighter and its 20mm cannon shells. The cast aluminum parts of the handle were made from melted Zero aluminum, and molded in plaster molds with plaster given by a Navy corpsman. In the pommel a small picture of my mother's face was inserted and sealed in with a small disc of Zero plexiglass.
That's a keeper.
