The steel double-sided hilt when the blade is folded, acting like a Flipper or like an Emerson hook, is complemented by a Thumb Stud, creating a triple quick-open system for the knife.

Handle - full-size with a length of 5", similar to assault knives. The anodized aluminum grip liners are finished with a non-slip texture for a secure grip.
