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.
