It features a wharncliffe blade with a blunt tip in order to cut free trapped victims without cutting them in the process. A variant with a pointed-tip designed for police use exists, known as the P-SARK (Police Search and Rescue Knife). Contents 1 History 2 Specifications 3 References 4 External links // History After a helicopter crash in 1999, which resulted in the deaths of six Marines and one sailor, the United States Navy performed an assessment of their equipment and decided, among other things, that they needed a new search and rescue knife.[1][2] The Ka-bar knives issued to the SBUs (Special Boat Units) had catastrophically failed to cut the Marines free from their webbing.[1] The Navy went to Emerson Knives, Inc., where the owner, Ernest Emerson, designed and fabricated a working prototype within 24 hours.[1] The Navy found that the knife met their needs, and the model was dubbed the "SARK" (Search and Rescue Knife).[2] The SARK is a folding knife with a wharncliffe-style blade and a blunt tip designed so a rescuer could cut trapped victims free without stabbing them. Seeing another need in the police community, Emerson replaced the blunt end of the SARK with a pointed end and named it the "P-SARK", or Police Search And Rescue Knife. The Ontario, California Police Department consulted Emerson to produce written policy for the carry and deployment of the P-SARK knives in their department.[3] In 2005, the Navy changed the requirements on the SARK to incorporate a guthook on the back of the blade for use as a line-cutter.[4] Emerson made the change on this model, which was designated the NSAR (Navy Search And Rescue) Knife and only made available to the United States Navy.[4] Specifications The SARK, PSARK, and NSAR, like all of Emerson's knives are made in the USA. All three models feature a wharncliffe shaped chisel-ground blade that is 3.5 inches (89 mm) long and hardened to a Rockwell hardness of 57-59 RC. The handle is 4.7 inches (120 mm) long, making the knife 8.2 inches (210 mm) in length when opened. The blade steel is Crucible's 154CM and is 0.125 inches (3.2 mm) thick. The butt-end of the knife is square-shaped and features a hole for tying a lanyard. Some models are made with partially serrated blades to aid in the cutting of seatbelts or webbing. The handle material of the SARK is composed of two titanium liners utilizing a Walker linerlock and a double detent as the locking mechanism. The reasons for using titanium as a linerlock material were due to its exceptional strength-to-weight ratio and corrosion resistance.[5] The handle's scales are made from black G-10 fiberglass, although models were made for a few years utilizing green G-10. A pocket clip held in place by three screws allows the knife to be clipped to a pocket, web-gear, or MOLLE. Each model is equipped with Emerson's Wave opening mechanism.[1] The Wave is a small hook on the spine of the blade designed to catch the edge of a user's pocket, opening the blade as the knife is drawn.[6][7] References ^ a b c d Combs, Roger (2004), "Emerson Knives", Knives Illustrated 18 (2): 36–41, 65–69 ^ a b Covert, Pat.
