Developed in the 1860s by A.J. Peavey, the Peavey Knife Pistol is a multi purpose knife, pistol and alarm gun. In addition to the 2 5/8 inch knife blade and the conventional folding trigger, the pistol is pre-rigged to accept a trip line (not included) for attachment to a door, window, chest or other moving object. Additionally, the patent form describes stabbing the knife blade into a door frame so the door will strike the trigger when opened as an alternate means of setting the trap. When opened, the item is 7 inches overall, with the pistol mechanism running the length of the body and numbered to match, the patent dates stamped on the hammer, and a pair of smooth hardwood grips.

Fine overall. The metal shows an attractive mixed gray patina with some shallow pitting, and the brass shows a deep antique color. The very good blade is sharpened, with a few nicks on the edge. The grip panels are also fine, with a few small scattered dings. Mechanically excellent.
