The XL is classy...it moves well, looks right, walks the walk, and talks the talk. It is not just a larger version of a Twitch. It is serious business that can more than get the job done. This is a high-tech statement of sophistication with all the bells and whistles that you expect from the designers at SOG. The fine construction comes together to make the XL one of the most practical and beautiful knives that we have ever handled.
S.A.T. (SOG Assisted Technology) brings the standard lockback knife (which is one of the oldest known knife locks on the planet) into the 21st century. This new concept will change your idea of what folding knives can be. Once the operator has initiated the blade opening action, S.A.T. propels the stainless steel blade out and firmly locks it into place. We warn you...this blade action is addictive. Play with it once, and you'll be opening it again and again. We have even included a built-in safety that either locks the blade closed or can double lock the blade open.
SOG Assisted Technology SOG Assisted Technology works through the balance of opposing high-tension coil springs. As one opens the blade the force to propel the knife open becomes greater than the closing force and the blade will open on its own. The end result propels the blade out once the operator has initiated the one-handed opening action. S.A.T. works so well that right-handers can use their left hand equally well to open a folding knife (of course this works oppositely for lefties).
Cryogenic Heat Treatment SOG's unique cryogenic heat treatment process increases the toughness and wear resistance of our blades. Taking the knife slowly down in temperature to less than -300°F and then back to room temperature. This stress relieves the material on an atomic level and increases overall strength as well as edge retention. Knife edges stay sharp longer with significantly less micro-fracturing and edge-chipping. Its this dedication to making your knife SOG sharp that sets us apart from the rest.
