The service men and women of the coalition forces in the Middle East and Afghanistan require cutting tools that can stand up to the harsh demands of the desert. This Carson Desert Tactical Folder from Columbia River Knife & Tool has been developed specifically to blend into the desert environment. The M16-14ZSF features a super rigid InterFrame build with 420J2 stainless steel liners, threaded stainless steel back spacers and Desert Camo pattern glass filled nylon scales. The blade is a non-reflective bead-blast finished AUS 8 stainless steel. It blends and almost disappears in the desert. The tactical SF model features two Carson Flippers, resulting in a true hilt when the blade is opened. The Big Dog glass filled nylon version has a 3.875 in. (98 mm) blade and full-size handle with a pommel which is exceptionally powerful in tactical situations. Weight is a hefty 6.3 oz. (179 g). It also features an automated liner safety. Automated liner safety is the locking liner safety innovation taken to the next level. The automated liner safety sets a pin between the locking liner and the frame. This pin acts as an additional layer of safety, so the locking liner is less likely to disengage during use. To close the knife, pull the red buttoned safety lever back, slide the locking liner over and fold the blade into the closed position. Want one of the most secure safety systems on the market? The choice is automatic. One-hand opening and closing is quick and smooth, the result of precision tolerances and lubrous washers at the blade pivot. The dual ambidextrous thumb studs with checkered surfaces provide instant access in any circumstance. The blade has Combined Razor-Sharp and Triple-Point Serrated edges. Model: M16-14ZSF.
