The Gill Harness rescue tool is a must-have for quick help in emergency situations. It includes a serrated blade edge, webbing cutter and a shackle key. The shackle key fits most medium sized shackles. The handle is made of G10 composite material for maximum grip in wet or dry conditions. Made of 420 stainless steel, with a titanium coating, the rescue tool is extremely durable and corrosion resistant. Due to its flat, low profile design, it fits into almost any pocket, from harness to life jacket. And if that's not an option, the nylon sheath supplied with the knife allows for easy carrying.
