Custom knifemaker and Knifemakers’ Guild member Kit Carson is widely known for his M16 design, but since 1990 Kit’s most consistent selling custom model has been his classic M4. In his usual unassuming manner, Kit says, “I guess you’d say it’s my flagship custom. It’s simple, with form following function. No tricks that look slick but aren’t worth a flip in your hand. I’ve made many variations on it, from exotic collectibles to working tacticals, in maybe 20 versions. But I still get more and more calls to make the M4.”

So finally, here is the production CRKT M4 that you can afford to carry every day, anywhere.
Features patented OutBurst assisted opening, and patented and exclusive AutoLAWKS which automatically actuates when the folder is opened and locked, creating a virtual fixed blade instantly for the ultimate in safety.

The patented OutBurst assisted opening mechanism instantly springs the blade fully open after you have opened the blade about 30 degrees. Has dual thumb studs for ambidextrous one-hand opening and bronze and Teflon bearings at the adjustable blade pivot for smooth, fast action.

The blade is a high-hollow-grind drop point of premium AUS 8 stainless steel in a bead-blast finish. Developed by Oregon City, Oregon, knife designer Tom Veff, the serrations are wide and angled at 60 degrees to the edge. The resulting cutting points bite instantly and dig deep upon contact, slicing smoothly and effortlessly.
The heavy-duty InterFrame build is true to Kit’s design, with dual stainless steel liners, one locking, and a 6061 T6 anodized aluminum back spacer. Also features brushed stainless steel bolsters are inset with textured black Zytel scales.
