Our aluminum InterFrame build SF folders share a unique design offering a combination of Carson Series features requested by military procurement specialists. The deep-bellied spear point blades were specified because they offer maximum strength. The open build allows two Carson Flippers to be incorporated, resulting in a true hilt — very rare in folding knives.
M21™-14SF Aluminum. Our production aluminum frame SF is based on Kit Carson's custom designs, with contoured handles of black, hard anodized 6061 T6 aluminum, with a perimeter radius. Stainless steel locking liners with friction grooves give positive locking. Blade steel is AUS 8 stainless with a Combined Razor-Sharp and Triple-Point™ Serrated edge.
Blade, frame and hardware are non-reflective tactical black. The blade receives a black titanium nitride coating for maximum corrosion resistance. Kit's trademark dual checkered thumb studs are standard. One-hand opening and closing is quick and smooth.
It also features our exclusive patented (1) AutoLAWKS™ automatic safety, which turns the folder into a virtual fixed blade automatically.
All knives in this series are equipped with clip options that allow four-position carry on belts or webbing. Caution: These knives are not designed for tip-up in-pocket carry. They are special knives, designed by the military for special forces use.
