The TDI Sidelock is a rugged folding knife from Ka-Bar! In extreme close quarters encounters where a suspect is attempting to take an officer's handgun, or an officer cannot access his handgun, the TDI knife is available as a "last option" knife. The TDI Sidelock features a bolstered handle with skeletonized G-10 scales and a stainless steel liner lock frame for tight, reliable lockup. The black finished 5CR stainless steel blade has a plain cutting edge. The thumb hole on the blade makes for simple one-hand operation. The pocket clip is tip-up and reversible for left of right hand carry.
