This is the NRS Pilot Knife for Freshwater Boating and Rescue Features: An excellent knife for freshwater boating and rescue (for saltwater use, choose the NRS Titanium Pilot Knife). The low-profile, quick-release Thumbs Up Sheath(TM) stashes fixed blades away securely and releases with a one-handed flick of the thumb. The sheath attaches firmly to a PFD lash tab; lanyard attachment point on the knife handle further safeguards against losing a blade in rough waters. Lanyard attachment point doubles as a valve wrench for an oxygen tank. The partially serrated edge covers all your cutting needs. The &';reverse scallop&'; serrations facilitate severing tough fibers. An asymmetrical handle and blade, along with the blunt tip, ensure proper blade orientation and help prevent injury. Jimping along the top of the blade edge secures thumb placement and prevents grip slippage. All weather G10 handle with hand contouring and comfortable, rubberized grip deliver maximum blade control in wet environments. Tumble polish blade of 420 HC Stainless Steel Blade length: 3.6" Total length: 7.25" Handle material: Glass-reinforced polypropylene w/rubber overlay Sheath material: Glass-reinforced polypropylene w/rubber touch points Professional and recreational boaters love the extra length and practical features of the Pilot Knife. Purpose-built for performance on freshwater and to pair with a PFD but so versatile that you&';ll keep one in the car, the camp bin, and the garage. "
