For tactical, general use and dozens of situations, the COAST DX338, RX350 and BX316 7Cr17 stainless steel knives are ideal. All feature COAST's exclusive, patented Double Lock safety system. The DX338 features a drop point blade and a liner lock. The RX350 is designed by world-renowned knife maker and inventor, Ron Lake, and has COAST's patented Max-Lock system that completely secures the blade when it is closed, and double locks the blade when it is open. The RX350's drop point, partially-serrated blade is incredibly strong and corrosion resistant. The BX316 has a rubberized non-slip grip over a fiberglass-reinforced nylon frame. The rubberized material and deep finger grooves nearly eliminate slipping, even when wet, and the blade's oval cut-out makes one-handed opening easy, with either hand.
