For years, Kit Carson"s M16 designs have been the most popular Columbia River Knife & Tool (CRKT) series. And our Zytel version has built the largest user base of all. These knives are built for function, not fad. And they are exceptional values.They use our very successful InterFrame construction, tough, textured Zytel scales over a 420J2 stainless steel liner InterFrame. We overbuild it for rigidity, using solid Zytel back spacers. And we assemble the handle with superior offset Torx fasteners. The handle is exceptionally rigid and fills the hand perfectly.
