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. CRKT calls 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.

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.

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. 

CRKT has also incorporated the 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.
