Also capable of acting as a hatchet or pick-axe, the Ontario SP16 SPAX Knife is one bad ass blade. Few know their cutting implements like Ontario, just ask two of their biggest customers, the US Military and US Government. The blades are epoxy textured and powder coated for added strength and have been hardened to 52-54 HRC, making them pretty much indestructable. Comes with a smart leather sheath too.
