Measuring 6 3/4 inches in the closed position, this pistol has a tapered octagon barrel in German silver positioned on top of a dual blade pocketknife. The 3 3/4 inch spearpoint knife blade is marked "V[crown]R/UNWIN&/RODGERS/PATENT" on the left ricasso and etched with floral scroll and "SELF/PROTECTOR" on the left. The 3 3/4 inch clip-point blade has the same ricasso markings but lacks the etching. The barrel is stamped with a pair of "crossed scepter" proofs on the upper left, "UNWIN&RODGERS/PATENTEES.SHEFFIELD" on the left, and "NON-XLL" on the right. Fitted with a lightly grooved vertical spur hammer, hinged ejector, and a folding trigger. A pair of checkered horn panels cover the sides of the body and a small compartment in the butt.
