(M2104) M21 Aluminum Folder - Designed by Kit Carson
M2104 description
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. AutoLAWKS, is the Lake and Walker Knife Safety innovation taken to the next level. AutoLAWKS automatically sets a pin between the locking liner and the frame. This pin acts as an additional layer of safety, so the locking liner is less likely to disengage during use. To close the knife, pull the AutoLAWKS red button lever back, slide the locking liner over, and fold the blade into the closed position.

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.

This knife is AMAZING. I bought this late 2009/early 2010. It has been in my pocket just about everyday since. The knife was JUST sharpened for the first time until today, as it has held enough of an edge. It has just about perfect balance. When I face any problem, this is the first thing I grab to provide a solution (really funny when you're cooking at a friend's place). People gawking at the size of the blade is an added bonus. My one and only EDC, I will continue to bet my life on it until the day I die. This knife has become a part of me.

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 vehicle escape. 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.
