Heavy-Duty Blade in a Classic Design

The OSI brings back the iconic sub-hilt fighter design, modernized into a single-edged blade that excels in controlled slicing and piercing. With a large 8¼″ flat-ground clip point, it delivers deep penetration and confident precision. Crafted from Japanese AUS-8A, the blade balances sharpness with effective corrosion resistance.

Balanced and Comfortable Handling

Its full-tang construction and ergonomically contoured Kraton handle, with integrated finger guard and sub-hilt, provide a secure, anti-slip grip even under combat stress or thick glove use. The handle is shock-absorbent, with deep checkering that enhances control and stability.

Resilient Carry System

The rugged Secure-Ex sheath uses a positive-locking button to secure the blade in any carry setup; belt-mounted, pack-worn, or paired on a boat. Drainage holes help prevent moisture build-up, while making deployment quick and intuitive.

Field-Ready Reliability

Tested extensively, including field dressing wild game like boar and buffalo, the OSI has proven its toughness and utility. Its single-edge format also makes it compliant in areas where double-edged knives are restricted.
