Here is Kit Carson's M16 Every Day Carry (EDC) with our glass filled nylon InterFrame build in black-on-black tactical dress. Our knife users told us. We heard you. So we set about to make the Z EDC the best value in the work and sport knife world. That starts with textured glass filled nylon scales and a dual stainless steel liner InterFrame. Assembled with glass filled nylon back spacers and Torx fasteners, the result is amazingly rigid. Glass filled nylon offers excellent toughness and resistance to solvents. Lubrous washers at the blade pivot and an adjustable pivot screw allow for perfect blade action.
