Rynoblade Knives Ruko Socius 3.25" 440C Black Oxide Folding Knife

The Rynoblade Knives Ruko Socius is a compact everyday-carry folding knife built around a 3.25" blade of 440C stainless steel finished with a non-reflective black oxide coating. Sized for dependable pocket carry, the Socius pairs its corrosion-resistant cutting edge with a black anodized aluminum handle accented by rubber inserts for a secure, comfortable grip.

At 3-1/4 inches of blade, the Socius covers the daily cutting chores - boxes, packaging, cordage, and general outdoor utility - without overcommitting pocket space. Its 440C steel is a proven choice for edge retention and stain resistance, and the black oxide finish helps cut glare while adding a layer of protection against wear and corrosion. The folding design keeps the edge safely tucked away during transport and is ready to deploy when the job calls.

The handle balances slim anodized aluminum construction with rubber overmolding for improved grip security during extended cutting sessions. Rynoblade's Ruko line delivers an affordable entry into everyday-carry folders, and the Socius covers the essentials - solid 440C steel, a useful blade length, and a grippy two-material handle - in a compact, carry-friendly package ready for daily duty.
