For years, Kit Carson's M16 designs have been Columbia's most popular series. And the Z version has built the largest user base of all. These knives are built for function, not fad. And they are exceptional values. The M16-02Z and M16-12Z are tough little bulldogs, with 3.00 in. dual grind Tanto-style blades. They use the very successful InterFrame construction -- tough, textured glass filled nylon scales over a 420J2 stainless steel liner InterFrame. It's overbuilt for rigidity, using solid glass filled nylon back spacers. And the handle is assembled with superior offset Torx fasteners. The handle is exceptionally rigid and fills the hand perfectly. Tough AUS 8 high-carbon stainless steel is used for the blades to give greater everyday utility, and you can choose 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, especially when wearing gloves, but acts as a blade guard when the blade is open. The automated liner safety is the locking liner safety innovation taken to the next level. The automated liner safety sets a pin between the locking liner and the frame. This pin acts as an additional layer of safety, so the locking liner is less likely to disengage during use. To close the knife, pull the red buttoned safety lever back, slide the locking liner over, and fold the blade into the closed position. Want one of the most secure safety systems on the market? The choice is automatic. All styles have lubrous washers and a removable stainless steel clothing/gear clip. Think of the M16-Z as a Clydesdale - ready to rush a knight into battle or pull a beer wagon. Every day. Day after day.
