M48 Liberator Falcon Karambit From the new Liberator series, United Cutlery’s M48 Falcon Karambit Knife is another triumph of tried and true ancient design reimagined into a modern, tactical weapon. The ergonomic, grippy handle has injection molded nylon handle scales, secured to the full-tang with heavy-duty screws. The traditional open-ring pommel has a point on it to use as a second line of self-defense against an assailant.
