I designed the ATCF in 1986-87 inspired by my experience with military and security personnel in Central America and the United States. 

The ATCF was the first tactical knife to be fully assembled with screws instead of pins and rivets.
I invented the thumb disk to facilitate opening with both hands. This became a widely copied feature of the ATCF and is used on many other knives by manufacturers around the world.

The ATCF was the first pocket knife to use a checkering on the top which, along with the guard, provides protection and a firm grip. 

The ATCF is one of the most copied knife shapes in the knife world, and as I often like to proudly say, "The ATCF is the shape...that shaped the whole industry!"

CRKT M16-13 Desert Spear Point Folding Knife M16-13ZM has been developed specifically to blend into the desert environment. This CRKT knife features the super rigid InterFrame build with 420J2 stainless steel liners, threaded stainless steel back spacers, and Desert Camo pattern glass filled nylon scales. The spear point blade of the knife is non-reflective bead-blast finished AUS 4 stainless steel, crafted into a partially serrated combo edge that blends and almost disappears in the desert. The Columbia River M16-13 Desert Combo Edge Folder Knife is ideal when weight and bulk must be kept to a minimum, and it comes with a removable, single position clothing/gear clip for easier carrying. It also features Columbia River Knife & Tool's exclusive patented AutoLAWKS safety, which automatically turns the folder into a fixed blade when the blade is opened and locked. One-hand opening and closing is quick and smooth, the result of precision tolerances and lubrous washers at the blade pivot, and the dual ambidextrous thumb studs with checkered surfaces provide instant access in any circumstance. For a folding blade knife that's at home in the desert, choose the Columbia River Knife & Tool M16-13 Desert Camo Nylon Handle Folding Knife.
