The deep-bellied spear point blade with recurve 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 it's length for maximum strength. Lubrous washers at the blade pivot assure velvety-smooth one-hand opening and closing, using Kit Carson's trademark dual chequered 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.
Incorporated also is the * 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.
