Drawing from a unique design specified by military procurement specialists, the CRKT M21 SF series offers a combination of features optimized for tactical use. The aluminum InterFrame construction of these folders provides a strong and reliable build.
The M21-14SF Aluminum is a production model based on Kit Carson's custom designs. It features a deep-bellied spear point blade, chosen for its maximum strength, made from AUS-8 stainless steel. The blade has a hollow grind and a black titanium nitride coating for superior corrosion resistance, while the entire knife - from blade to frame and hardware - is a non-reflective tactical black. Kit's trademark dual checkered thumb studs and two Carson Flippers allow for quick and smooth one-handed opening, with the flippers creating a true hilt when the blade is deployed.
This pocket knife features contoured handles of 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 provide a positive lock. The M21-14SF also includes CRKT's exclusive patented AutoLAWKS automatic safety, which turns this flipper knife into a virtual fixed blade when open. All knives in this series are equipped with a clip that allows for four-position carry on belts or webbing, making them special tools designed for special forces use.

Columbia River CRKT M21-14SF Carson Special Forces Flipper 3.875" Black Combo Blade, Black Aluminum Handles
I read the reviews of this knife and with my experience with this manufacturer I decided to put it in my wish list. I sold CRKT knives for a few years prior to being on the other side of the counter. I bought more than a few Benchmade and Spyderco knives in the meantime. I decided the handle issue..slippery feel..could be remedied with stippling if needed. I ordered it...or really backordered it and waited it out. I had almost forgot and then received the ship notification and then....It came in and the only thing I would do differently is order it sooner. Maybe they made the handles a little coarser or changed the finish but it feels good to me. It really could not open faster but it closes after an additional step, which is a good thing. Because it is sharp and it stays sharp.

Pros: Weight, Ease of Opening, Handle Material
Cons: Pocket Clip
far away from SF knife
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.

Very sharp,very cool. I actually bought both of them, the one with the G10 handles and this one. I am a prepper and one is none, so both of them are mine now. Aluminium handles are smooth and have a quality feel to them. however ,with sweaty palms they might get slippery. But the blade is razorsharp and of top quality, I highly recommend this knife. by the way:The trick you see on how to open the knife works really cool.
