Tactical operators have long admired the superior strength of the Tanto blade design. It’s the knife of choice for many Border Patrol and U.S. Customs agents, because it’s tough enough to cut through many automotive materials. The NRA SOG Twitch XL Tanto is our testing team’s new favorite knife --- no one can put it down. Just a slight nudge of one of its dual thumb studs or the extended blade “twitch kick” will engage the patented S.A.T. (SOG Assisted Technology). The Twitch opens to its full 7.5” length in a flash! When closed, the reversible bayonet pocket clip will keep it always at the ready, and SOG’s locking safety works double duty, while the knife is open AND closed. The Tanto-style blade is 3.25” long and .125” thick. And, it’s cryogenically heat treated for increased toughness and wear resistance. The AUS-8 stainless steel blade has a smooth, black titanium nitride coating that provides dramatic contrast to the NRA logo etched on its surface. Handle is black, hard-anodized 6061-T6 machined aluminum. This is one of the most practical knives we have ever handled. Weight: 4.2 oz. Includes manufacturer's lifetime warranty. Assembled in USA.
