Constructed of 440 C, hardened stainless steel, the 5 Rescue Hook is built to last in any environment. At the slicing end, a shrouded, scalpel-sharp edge provides rapid cutting. The tool fits neatly in your hand, and the finger ridges along the back edge ensure a good grip. The finger hole in the middle doubles as a bottle opener. The 5 Rescue Hook comes in a wide variety of sheaths, including ones with a quick-release Velcro fastener.
