This crossbar locking knife from Kershaw checks all the boxes. It has a flipper, a reversible deep pocket clip, an easy crossbar blade release system, quality D2 tool steel blade and a great price! This mid-size folder features a comfortable glass-filled nylon handle with stylish, textured pockets. The Covalent deploys using a flipper on KVT ball bearings. The strong DuraLock crossbar system secures the blade in place using a solid steel crossbar. The drop point blade with a flat grind and D2 steel makes it a go-to cutter during work tasks. To close the knife, pull back on the ambidextrous DuraLock, and your fingers will never enter the path of the edge. An extra-deep-carry pocket clip is reversible for left or right carry. It's all-business. It's reliable. The Covalent is undeniably irresistible.
