RAF Mk.III flying suit survival knife
Stores reference 22c/1278106. Almost certainly manufactured by Joseph Rodgers of Sheffield. Approximately 21cm in length. Standard aircrew issue until replaced by the unpopular 'J' cutter tool. Flat profile gravity knife with a composite handle containing a spring lock mechanism activated by two levers on either side of the hilt. This mechanism locks onto a stud on the sheath and so retains the knife. The blade is of stainless steel, curved, and measures approximately 10cm. The knife was worn in a metal scabbard /sheath, stores reference 22c/4466607/13 attached to a cloth patch, stitched upside-down on the flying coverall leg. This enabled the knife to drop out on a lanyard should the wearer need to cut rigging lines of a parachute canopy in an emergency situation. We have a small quantity complete with scabbard in mint unissued condition. Each is marked with reference numbers, war department broad arrow and '98 date.
