www.sog-knives.net Looking to impress? Then get caught carring the SOG Twitch XL Tanto, model TWI-201. With the SOG Assisted Technology packed inside the handle, one thinks nothing but serious when this blade springs to life. Activated by pressing the lever on the back or pushing the thumb stud, the AUS 8 tanto blade comes flying out with a hard click. The blade is held in place and released by the lock back mechanism in the spine. A graphite handle on the SOG Twitch XL Tanto makes a nice compliment to an already snazzy knife. And to top it off, the model TWI-201 has a reversible pocket clip with the SOG name scrolled into it.
