Extrema Ratio Aero Nitrogen Black Blue

The Aero is a compact fixed-blade knife built around a 2.75″ nitrogen steel tanto blade with a MIL-C-13924 burnished finish, reaching 6.88″ overall. The black anodized aluminum handle features a full, extended tang and includes a thumb pull for quick deployment, along with a lanyard hole for attachment. A pair of cut-resistant rubber loops mounted on the sheath enable horizontal belt carry, and the knife ships in a black Kydex neck sheath. Blue accents on the handle provide visual distinction.
