The Satre F Nitrogen Orange Black is an everyday carry folding knife built to be truly pocket-ready: compact profile, instant flip opening, double steel liners, Liner-Lock blade lock, and a Deep Carry clip for discreet carry. The milled scale window lets the blade color show through when the knife is closed, giving the Orange Black version a very strong visual identity. The Nitrogen steel versions in the line are described as offering very high corrosion resistance and minimal maintenance.

On the technical side, the knife weighs 98 g, measures 174 mm overall, has a 72 mm blade, and 3 mm blade thickness. The blade is made of Nitrogen steel with MIL-C-13924 bluing and a flat grind; the handle is made of anodized anticorodal aluminum.
