This Marfione Custom Tachyon III butterfly trainer has a stonewashed trainer blade made from M390 stainless steel. It is equipped with titanium handles in a stonewash finish. Includes box with certificate of authenticity and zippered nylon pouch. New from maker.

The latest generation of the Tachyon butterfly knife, the Tachyon III, has arrived, and it's insane! It's quite different in construction than the previous Tachyon models with milled, integral titanium channel handles, a spring latch, and retractable pocket clip. Designed to stay out of the way while you manipulate the knife, the minimal pocket clip is the first of its kind. What would a brilliant design and premium materials be without that smooth action you crave? The Tachyon III exceeds expectations with an advanced ball-bearing pivot assembly.
