*USA, c.1960, DESCO Diver’s Knife and Brass Scabbard*
A fine and complete original DESCO U.S. diver’s knife, dating from around 1960, almost certainly manufactured by DESCO (Diving Equipment & Supply Co., Milwaukee).
The knife measures 13½ inches (34.3 cm) overall, with a 7-inch (17.8 cm) blade — one edge sharpened, the other finely serrated for rope or net cutting. The blade screws securely into a heavy all-brass scabbard, forming a watertight and pressure-resistant seal. The grip is turned from maple wood, with deep concentric grooves for secure handling underwater. The brass pommel incorporates a slotted vent screw, and the scabbard features the classic flanged throat and tapered drainage tip, both hallmarks of DESCO-pattern manufacture.
Historical Note: The DESCO-pattern diving knife evolved from the wartime U.S. Navy Mk V diver’s equipment suite, produced by firms such as DESCO, Morse, and Craftsweld for both military and commercial use. Designed to resist corrosion and withstand the rigours of deep-sea salvage and ship maintenance, these knives were supplied worldwide to naval and civilian divers through the 1950s and 1960s. The screw-in brass sheath provided complete watertight protection — a design shared with the classic Mk V diving helmet and tools.
Provenance: Former property of Chief Petty Officer Stephen Laurence “Darby” Allan (1958–2010), Royal Navy diver and mine disposal expert, whose career encompassed deep-water salvage, ordnance clearance, and diving instruction during the Cold War period.
