Microtech's OSS Cobra features a lever lock design to deploy the blade.  The lever must be rotated forward and pressed for activation and unlocking.  The action is fast, smooth, and virtually silent.  The internal spring mechanism is a dual leaf spring design.

    Available blade styles will be a double-edge style blade with false top and a bowie style blade.  Handle materials will be available in G-10 (multiple colors) and carbon fiber.  Bolsters and spacers are titanium.
