Engineered by award-winning knife designer Mike Vellekamp of Blade-Tech, the fixed-blade Side Kick Boot Knife from 5.11 Tactical has an overall length of 5.5 inches with a 3.5-inch combo-edge modified tanto blade. The knife is constructed of quality AUS 8 blade steel with a 4 mm blade thickness. It’s coated with rugged black oxide, has a skeletonized handle and offers several carry options. Use 5.11’s injection-molded plastic sheath for boot, duty-belt, or web platform carry, attach it to an officer's 5.11 Tactical Vest, or use the included break-away bead chain for neck carry. This practical, lightweight back-up tool cuts fabric, line, nylon webbing, cardboard and sandwiches, and offers ambidextrous up/down/left/right options. Use the included Allen wrench to adjust the carry height of the knife, and turn oxygen tanks on and off with the handy 02 wrench in the blade.
