Important Read :

Designed with inspiration from the Okinawan Sai, to be a defensive melee weapon that would be more practical to carry and self-sheath.  The blade retracts to be eclipsed by the handle protecting its point making an integrated sheath.  It's one-button locking mechanism is designed to engage automatically in the open or closed position and must be pressed to unlock it from either end.
