CRKT M21 Special Forces Knives
After the success of CRKT M16 Special Forces series, CRKT received requests from professional knife users in the military and law enforcement for the larger "Big Dog" size with a more versatile blade shape. CRKT talked to the designer of the series, retired Sergeant Major and Knifemakers' Guild member Kit Carson, and the M21 special forces series is the result. The blade is similar in shape to the Carson M21, but with the addition of a second Carson Flipper on top, resulting in a true hilt. The blade grind is a deepbellied spear point with a Combined Razor-Sharp and Triple-Point Serrated edge on the M21-14SF model.
In addition to the original model with InterFrame build and aluminum scales, CRKT also offer this knife as the M21-14SFG with InterFrame build, G10 scales, and CRKT exclusive patented1 Veff Serrations. CRKT use premium blade steel on both models. A black titanium nitride blade coating protects against corrosion and gives a low-reflectance finish.
The series features CRKT patented2 AutoLAWKS safety, which provides fully automatic actuation. It immediately turns the folder into a fixed blade when the blade is opened and locked. The safety still allows the quick and smooth onehand opening and closing that CRKT Carson series is known for. The ambidextrous thumb studs with checkered surfaces provide instant access.
M21-14SF Aluminum. CRKT production aluminum frame SFs are 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.
M21-14SFG G10. This model features a stainless steel InterFrame build with black G10 scales. Many operators prefer G10 because of its aggressive texture, light weight, and insulating properties in very hot and cold conditions. Now you have a choice. Blade steel is 8Cr14MoV stainless.
All knives in this series are equipped with clip options that allow four-position carry on belts or webbing tip up, tip down, left or right. (Caution: These knives are not designed for tip-up in-pocket carry.) The M21-14SF series is a
