Columbia River Knife & Tool® (CRKT®) is proud to introduce our new production Biotac™ fixed-blade carry system. Designed by noted custom knifemaker and inventor Ed Van Hoy, it uses nylon cord and a locking slider to place a knife in almost any inverted carry position desired. It is designed for carry of fixed-blade knives of all sizes which have a positive locking sheath with a detent or snap to securely hold the knife in place, such as those typically made of glass filled nylon or Kydex®. Carry options include 1. Standard carry around the neck, fully adjustable for length; 2. Bio neck carry with underarm retention; 3. Bio neck carry with halter retention; 4. Waist carry, left or right; 5. Under shoulder carry with underarm retention; and 6. Small of back carry with dual shoulder cords.
