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.
I've had this knife for 6 or 7 years now (I think). Mine was made in the USA. I'd be disappointed if they are no longer made here. This knife is tough as nails. The opener or lock has never failed. It holds an edge great but is easy to get razor sharp.

Outstanding knife. It is not small, but I use it professionally on-the-job, and the size is perfect. Smooth folding mechanism that, with the AutoLAWKS feature, assures me that it will remain open until I decide otherwise. Great steel for the blade insofar as holding a sharp edge is concerned. My only issues would be that CRKT didn't support additional American jobs by keeping the production of all their knives in the U.S. (for a $130 knife, I don't care to see "Taiwan" stamped on it), and lastly, like some other companies that charge less for their knives, it would be nice if CRKT offered free sharpening of the knife when returned to the manufacturer at customer's expense. Outside of those items that don't reflect on the knife itself, the M21-14SF is a solid performer and recommended
