After the success of our M16 Special Forces series, we received requests from professional knife users in the military and law enforcement for the larger "Big Dog" size with a more versatile blade shape. We talked to the designer of the series, retired Sergeant Major and Knifemakers' Guild member Kit Carson, and M21 SF 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 deep-bellied spear point, which leaves an exceptionally strong full-width spine which extends down 80% of of the blade length.
The blade has Combined Razor-Sharp and Triple-Point Serrated edge maximum versatility when cutting through rope, cord, underbrush or netting.
Blade steel is premium AUS 8 stainless steel, which offers an optimal combination of strength, toughness and edge-holding ability. A black titanium nitride blade coating protects against corrosion and gives a low-reflectance finish.
The M21-SF also features our new patented* AutoLAWKS knife safety, which provides fully automatic actuation. Based on the Lake And Walker Knife Safety (LAWKS), it immediately turns the folder into a fixed blade when the blade is opened and locked. Release the LAWKS lever, release the locking liner, and it folds to an easily carried length. You have the advantages of a fixed blade with-out the disadvantage of a costly sheath carry system.
AutoLAWKS still allows the quick and smooth one-hand opening and closing that our Carson series is known for, the result of precision tolerances and lubrous washers. The ambidextrous thumb studs with checkered surfaces provide instant access in any circumstance. The CRKT production aluminum frame SFs are based on Kit Carson's custom designs, with contoured handles of textured, black, hard anodized 6061 T6 aluminum, with a perimeter radius for a comfortable grip with or without gloves. Stainless steel locking liners with friction grooves give positive locking.
Each knife comes with two stainless steel black corrosion resistant clothing/gear clips, extra screws and a Torx tool, allowing four-position carry on belts or webbing- tip up, tip down, left or right.
The M21-SF is a true advance in tactical locking liner folders, and is also an outstanding value.
