Sark is also an island in the British Channel Island group. The SARK (Search and Rescue Knife) or NSAR (Navy Search and Rescue) is a folding knife designed by knifemaker Ernest Emerson for use as a search and rescue knife by the US military. It has a hawkbill with a blunt tip in order to cut free trapped victims without cutting them in the process. There is a variant with a pointed-tip designed for police, known as the P-SARK (Police Search and Rescue Knife).
