CRM2114SF: M21-14SF - Combo Edge - Designed by Kit Carson
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.

Cons: None
Great Knife!
Awesome folder, kept its edge for a decent amount of time, fairly easy to resharpen, my go to EDC knife now, replaced a Kershaw. High quality construction, handle is ok, not sure if I should have gone with G10, this plain stuff works ok.

Pros: Blade Material, Overall Quality, Pocket Clip, Lock Ease of Use, Weight, Ease of Opening, Blade Sharpness
Cons: Handle Material, Lock Type, Handle Feel, None
The only downside to this knife is that the handles are a bit slippery. In hindsight i would have gone with the G10 version of this knife. Other than that i love it. Super fast opening and very smooth action. The AutoLAWKS is a pain. Regular LAWKS doesn't bother me but the Auto version is the first thing i am going to remove.

Cons: Lock Ease of Use, None
Great EDC Knife
I purchased this knife as an EDC to add to my collection. It's extremly well made, easy to hold and open. Closing the blade is somewhat difficult which maybe a concern to some. The blade is very sharp with a thick back bone very strong. The LAWKS locking system makes this folder almost a fixed blade. The flipper is quite fast almost as fast as my assisted folders ! I love this knife.
