The Ontario SK-5 Blackbird has the design of a pure bushcrafter; stripped down to just what a useful knife needs and nothing else. The Blackbird SK-5 blade is crafted from 154CM. This steel is American made, known for its superior toughness, edge-retaining ability, sharpness and corrosion resistance. The SK-5's spear point blade is an excellent working profile and features a full-length flat grind.

The edges of the G-10 Handle are rounded to provide a comfortable grip and are secured to the knife tang with stainless steel Allen screws.

The Ontario Blackbird SK-5 comes with a MOLLE compatible sheath that features a rigid protective insert. The sheath also features a belt loop so that it may be worn on the hip in the traditional belt mount configuration.
