CRM2114SFG: Carson M21™ Special Forces - Black G10 Handle - Combo Edge
Columbia River Knife & Tool

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 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 deep-bellied 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, for 2008 we’re offering this knife as the M21-14SFG with InterFrame build, G10 scales, and our exclusive Veff™ Serrations. We 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 our patented* 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 one-hand opening and closing that our Carson series is known for. The ambidextrous thumb studs with checkered surfaces provide instant access.

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 8Cr14 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 true advance in tactical locking liner folders, and is today an even better value.

About the Knife Designer
Kit Carson of Vine Grove, Kentucky, is a retired professional soldier, rising to the level of Sergeant Major. He has made knives for 30 years and has been a full-time knifemaker since 1993. He is a voting member of the Knifemakers’ Guild. Kit has been an avid hunter and fisherman for over 40 years, growing up enjoying the woods and trout streams in the mountains of north Georgia. About his philosophy of knife design, he says: “I strive to follow form and function in the knives I design and build. My reputation has been built around solid working knives, both fixed blade and folders. All the time spent outdoors as a young man and the time spent around the world with the Army has strongly influenced the knives I create.” Nothing reflects this approach more than the Carson Design of our M16 series, which is built for function, not to follow fads. This highly successful knife series was named one of the Top 10 Factory Tactical Folders of the Decade by Blade magazine. The M16-14M recently won a comparison test conducted by Germany’s Messer magazine.

could be tactical but not SF at all
Fantastic idea but very poor execution. BTW handle shape is beautiful and it’s very nice to handle it in any way. Cross guard is also beautiful solution not just to protect but also to give a fast and smooth flip open action. But: 1. AUS 8; not so great as some other steels on the market (I’d pay far more for a quite better steel than AUS 8), 2. no sense at all to call “Special Forces” a knife with the blade serrations on the hottest spot you actually need, not mentioning that for the most of “SF” purposes you don’t need serration at all (actually you don’t want it at all); same could be apply for field sharpening (instead of being able to use just a one simple stone due serration you need one more extra tool eg. sharpening rod)… considering the field work, teeth on the top of serration will go off very quickly, especially Veff serration will lose it’s aggressive teeth pretty quickly (after every re-sharpening just faster and faster); no SF would want any of those happen to his knife.Also, having a few versions of M21 (14SF, 14SFG, 14G etc.) I have to notice that you CAN’T combine parts of one with any of others, even same versions seems as have a different measurements, sizes and length of liner lock, pivot hole… even pocket clip is different in size, shape and measurements as well as all of the screws. So if you think to buy a 2-3 models to make your preferred configuration you’ll be very disappointed. As I said, fantastic idea – very poor execution.
