[RUSTPROOF X EDGE HOLDING]

At 8.50" OAL with a 4.375" blade, this mid-sized submersible fixed blade delivers exceptional cutting performance without adding unnecessary weight. Its 3D-contoured, textured epoxy handle provides a secure, non-slip grip in wet or gloved conditions, making it ideal for divers, sailors, anglers, overlanders, and outdoor professionals.

Whether you're diving, portaging, boating, navigating coastal terrain, or trekking through rain-soaked jungles, the Nautilus Alpha stays sharp, stays strong, and stays trustworthy. Each knife includes a rugged Kydex sheath with TekLok for secure carry in any environment.

Available in Black or Orange.

Pro Tip: After saltwater exposure, give the hardware and eyelets a quick freshwater rinse to keep the Kydex sheath in top condition.
