4" closed length. 3"  Assisted Opening  High Contrast Damascus Steel Blade. Features an index trigger that serves both as an ambidextrous opening aid and as a finger guard when the knife is open. With a simple push on the index trigger, the closed knife quickly springs open using The Ken Onion Speed Safe torsion bar technology to propel the blade to an open and locked position.
