The Nautilus is the most innovative Squid Industries product yet and is the first production balisong trainer to feature a channel-liner design with handle overlays. 

Manufactured and assembled in the USA


  • 6061 T6511 Aluminum Channel Liner Handles with G-10 fiberglass laminate overlays for increased grip and durability
  • Finely tuned bushing pivot system for nearly zero handle play and maximum smoothness
  • Chamfered spine for enhanced comfort
  • Tapered handles for more control
  • Quiet tang pin system for nearly silent flipping

The Inked Nautilus features a DLC coated blade. DLC, or Diamond-Like Carbon, is an extremely hard coating used to reduce friction, wear, fretting, galling, and corrosion. Not only is it tough, but it's also incredibly thin and comes in at under 2 microns in thickness.
