CRKT M21 Series Knives - We call the hefty M21 series with 3.875' blades, 'Big Dogs.' The swedged and recurved blade is ground to a spear point shape, using premium AUS 8 stainless steel in non-reflective frost finish to offer superior edge retention. The grind incorporates a false top edge and deep belly, yet retains a full width central spine for most of its length for maximum strength. Using Kit Carson's trademark dual checkered thumb studs which also act as a blade stop. M21 models feature the very popular 'Carson Flipper' blade extension, which aids opening and acts as an additional blade guard. Kit Carson's open build uses contoured handles of 6061 T6 aluminum, hard anodized charcoal gray. They are CNC machined with a perimeter radius for a comfortable grip with or without work gloves, skeletonized to reduce weight. There is a single stainless steel locking liner with friction grooves for positive locking. 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. We have also incorporated our patented AutoLAWKS? automatic knife safety into all M21 models, which converts them into virtual fixed blades when their blades are open and locked. Every model features a removable Teflon®-plated stainless steel clothing/gear clip. All fasteners, including the clip screws, are Torx®. So there you have it. If you love the Carson line, but your work tasks demand a deep-bellied blade, the M21 is the series for you. Same premium build, same functional features, same long life, same excellent value.

CRKT M21 Series Knives


I have the CRKT M16 and M21 series of knives. The M21 is pretty darn big for a folder, but very sturdy and overbuilt. My favorite is the DSFG, with the textured G10 scales, Carson flippers and Veff serrations. That one stays on my plate carrier full-time and has been through hell and back. The relatively exotic blade steel sharpens nicely and holds an edge well. M21s are too big for every day carry unless you're a really big guy or a lady with a lot of purse room, in my opinion, but, they are still great knives. If you want something for an EDC, the M16 is probably a better choice.

I love this knife! Very smooth transistion from the closed to the open postion and the blade lockup is solid, you will not think twice about it. The way the business end snaps into the ready position sounds clean. Easy to sharpen with no serated edges to try to work around. CRKT keep up the good work!
