Intricately designed by Gerber and Bear Grylls, the Ultimate Knife comes loaded with innovations you won't find in any other fixed-blade knife. The half-serrated, high-carbon, drop-point stainless steel blade is ideal for edge retention and cutting rope. Ergonomic, textured rubber grip ensures comfort and secure hold. Stainless steel pommel at handle's base for hammering. The nylon sheath is lightweight, military-grade, and mildew-resistant. A fire-starter ferrocerium rod locks into sheath while a striker notch is incorporated into back of knife's blade. The sheath also features an on-the-go diamond sharpener. Comes with integrated emergency whistle, land-to-air rescue instructions, and "Priorities of Survival" pocket guide with Bear's survival essentials.
