CRM2112G: Carson M21 G10 - Combo Edge
Columbia River Knife & Tool

We did it again. This G10 work knife series features premium materials, build, and finishes--all at a value price.

It began like a Christmas wish list. What if we could build Kit Carson's M21 series just the way a custom knifemaker would: with a G10 and stainless steel InterFrame build and a titanium nitride-coated premium stainless steel blade? What if we could bring it in at a very competitive value price? Just like a kid on Christmas morning, we got everything we wanted. And so can you.

Choose from two sizes, just like our original M21 aluminum series, in your choice of Razor-Sharp or our exclusive Combined Razor-Sharp and Veff Serrated edge grinds.

The swedged and recurved spear point blades are made of premium 8Cr14 stainless steel with a non-reflective black titanium nitride finish which gives maximum corrosion resistance.

There are many reasons custom knifemakers choose an InterFrame build with stainless steel liners and G10 scales in preference to aluminum or even titanium scales. First, the aggressive G10 texture gives unparalleled grip. Second, it is very strong. Third, it is lightweight. And finally, G10 is an insulator with a low specific heat. Therefore, it is cooler to grip in the beating desert sun, and warmer to grip at subfreezing temperatures.

These M21 models also feature the very popular "Carson Flipper" blade extension, which aids opening and acts as an additional blade guard.

Unlike the typical custom knifemaker, we are able to engineer our patented* AutoLAWKS automatic knife safety into all M21 models, which converts them into virtual fixed blades when their blades are open and locked.

As is standard practice on CRKT folders, Teflon bearings at the blade pivot assure velvety-smooth one-hand opening and closing, using Kit Carson's trademark dual checkered thumb studs which also act as a blade stop.

Every model features a removable Teflon-plated stainless steel clothing/gear clip. All fasteners, including the clip screws, are Torx. Liners, hardware and clip are black oxide coated.

So there you have the M21 G10 series. We call it a "premium value line." Everything you could ask for in a custom-quality work knife at a great price. Does that make us feel jolly? Ho, ho, ho!

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.

Pros: Overall Quality, None
Cons: Lock Type
Not what I expected
I use it as my EDC knife. Action is very nice and smooth, knife is built with quality only thing I have a thought time is closing it, I can't seem to get the one handed close always need two with the safety and stiff liner lock. Maybe get easier with time as it wears on but all in all 8.5/10!

One knife to rule them all
I am a carpenter, and project manager in residential home improvement, addition and remodeling work. I use this knife for EDC. It is my third CRKT Carson folder. I test/use it on everything. I use it every day from opening packs of various sorts, to slashing cordage or branches, unboxing, and cutting heavy duty lumber pack plastic straps by sliding the knife flat and twisting with a quick upward jerk, never showing a sign of weakness even while keeping the pivot screw tension comfortable for opening ease. The serrations are amazing. Period. They cut deep, fast. I measure all other knives by what this knife can do. I don't expect it to do more than it was designed to do, but I bet my life on it. It goes everywhere with me and I feel naked without it. The aggressive serrations cut thru almost anything. One time when this knife was newer to me (about 6 years ago) I choked up on the blade a bit to cut some tape and the serrations cut my middle finger almost to the bone without feeling it (I say almost but I was afraid to open it and bleed all over the customers house). The knife still scares my brother. A self defense knife should not just be able to thrust. If someone grabbed me from behind by the throat, with one upward slice the serrations would have no problem going through a coat and filet the attackers arm, or slicing through a rope if around my neck, etc. The serrations not only slice, but pull the knife deep. I reversed the clip for "tip up carry" and a fast out of pocket flick of the assist tab make this easily a self defense tool. With endless practice for fun and function the knife is easy to operate even with the Auto-Lawks that all these sissies complain about. I love it. It is security. I trust it to never close on my hand. Take almost any liner lock and you can start to force close and see the liner move in a frightening manner. Not this knife. It's as good as a fixed blade from that standpoint. Side to side play after years of hard use and twisting against lumber pack strapping, wood carving hickory, etc. is minimal and acceptable still. I am writing this while looking for my next one. I am looking to buy one like this in the 3.8" and a 3" plain blade. Can't go wrong with it. You won't be disappointed. It would be hard to put the knife through more use than I have, unless you are one of those knife nerd jerks that brake knives on purpose just so they can be the food critic of knives.

Perfect EDC knife
This is my EDC knife. A friend gave me an m21 last year and i beat the crap out it daily. I recently lost it on a job and ordered another that same week. I just can't be without a strong, sharp edc knife. Thanks again! Great product and fast shipping!
