I was skeptical about the size and locking mechanism. Have the knife now almost a year and love it. Sharp a on the first day, ridiculously easy to clean - you can easily screw it by hand apart and wash it - the press/push/pull mechanism to arrest it in the sheath has mot let me down once in all possible dive positions. It holds nicely in the hand and strapped to the leg it’s generally easy to get to. Straps and sheath show hardly wear & tear. Also very good is the blunt point. It makes the knife better to handle and acts even as a tool to hold on to it put in crack in strong currents (only in rocky dead areas). Highly recommended.
