This Spyderco Sprint Run MANIX 2 knife features a textured carbon fiber handle and a CPM-154/S90V composite steel blade. The Manix 2 features Spyderco's Ball Bearing Lock, which operates around a free-floating ball bearing contained inside a custom polymer cage. The ball bearing's round shape allows the lock to self-adjust across a large surface ensuring smooth and consistent lock-up every time it is engaged. The Ball Bearing Lock is engineered to be self contained meaning there is no need for internal liners to support it, allowing the folder to be manufactured liner-free and extraordinarily light weight. Excellent condition.
