CRM2104G: Carson M21™ G10 - Plain 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.

A Big Ole' Blade
I carry my M21-04G every day and love it. Great utility blade, great for open boxes and cutting strapping. Some people think its too muck knife for EDC, but I feel it fits my hand well and rides nicely in my pocket. All in all I like my CRKT M21-04G

CRKT M21-04G Carson Design folding knife
The M21 is my everyday carry knife, its light, extremely strong and made with excellent steel that holds an edge. One hand opening and closing make this a functional easy to use tool. The modest price also means great dollar value, I like them so much I have boight three and give them for gifts to friends. Well done Mr. Carson for a well designed knife and thanks to KnifeCenter for the fast delivery & service and low price.
