When a series like Kit Carson's aluminum-handled line has been so successful, it is bound to spark calls for variations. In this case, the request was for a deep-bellied spear point blade with recurve. We call the hefty M21-04 and M21-14 models 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. We offer both Razor-Sharp and Combined Razor-Sharp and Triple-Point™ Serrated edge grinds.
Lubrous washers 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.
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.
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 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.
I was the owner of a first generation CRKT M21-14. What a GREAT Knife It had multiple options for clip placement and had the manual LAWKS feature, which I really like. The blade belly and combination plain and serrated edge is perfect for precision cutting and for escape from seat belts in an emergency situation. The scales have a useful shape for breaking auto safety glass in emergencies such as a submerged
The current generation of M21 does not have the multiple options for mounting the clip only allowing for tip down carry that requires awkward manipulation before using the flapper for one hand opening. This is the deal breaker for me. The Auto LAWKS lock is another, though minor, annoyance.

I have carried the M16-04Z everyday since about 2003 without failure. Even "batoned" with it. I've put it through hell, really. A serious workhorse. I just recently purchased the Aluminum M21-04. I love it. It's a work of art. And I expect the same performance that the M16 gave me. WHY IS THE POCKET CLIP BELOW THE PIVOT SCREW??

This is my second M21. My first M21 was given to me by a friend which I used (and abused) doing construction and farm work through all four years of college. The M21 is just a great design

This is one of my favorites EDC knives. I own many different styles and brands from Cold Steel and Spyderco. This knife tops just about any other comparable model from other brands. It opens very quick and smooth. The flipper works great. The blade locks in very strong. I purchased a second knife just in case I lose the first one. Also this knife is better than the
M21-04G. It is definately worth the extra money. The workmanship is better. It is considerably thinner and lighter. CKT folks are great people to deal with.

This is a great carry knife. I am in the military and I always appreciate a good knife. This knife is extremely sharp, so when they say "razor edge", they mean it.

A solid, well built knife with a stout feel. It is sure to hold up to heavy use. It opens smoothly but requires just a little more inertia to open than a shorter lighter blade. The handle is smooth but there is plenty of knife to hold on to. It is heavier than many EDC knives so I'll only carry it when I may need a serious knife.
