The CRKT Definitive is one of the first to incorporate a Crossbar Lock. Designed to be fast, smooth, and (maybe most importantly) fidget friendly, the Crossbar Lock is fully ambidextrous, adding another layer of convenience to your new EDC knife. Featuring a 154CM blade, the Definitive is ready for any task you're likely to come across in your day to day. The Definitive's G-10 handle offers excellent grip in all conditions, ensuring that this knife will keep up with you no matter where you're off to.
