When we considered offering Kit Carson"s very popular aluminum M16 design in a more affordable build, we turned to our very successful InterFrame construction. Instead of aluminum handles, we use tough, textured Zytel scales over a 420J2 stainless steel liner inter-frame. We over-build it for rigidity, using a 6061T6 hard anodized aluminum back spacer. And we assemble the handle with superior offset Torx fasteners. The handle is slightly heftier and wider than the M16, but it is exceptionally rigid. To some of us, it actually fills the hand better. We use our tougher AUS 6M high carbon stainless steel for the blades to give greater everyday utility, and offer both Razor-Sharp and Combined Razor-Sharp and Triple-Point Serrated edges. All models feature the Carson Flipper, which is not only an aid to opening the blade, but acts as a positive blade guard. The M16-02Z and 12Z are tough little bulldogs, with dual grind Tanto-style blades. All styles have Teflon bearings and a removable Teflon plated stainless steel clothing/gear clip. Which M16 design is right for you? It depends on the task. Think of our original aluminum-handled M16 as an Arabian stallion-purpose bred and lightweight. Think of the M16-Zytel as a Clydesdale-ready to rush a knight into battle or pull a beer wagon. Every day. Day after day.
