Fast, thick, and tough, the Fullback AO is designed as a workhorse for the modern-day knife enthusiast. Featuring a robust 3.25 mm-thick Wharncliffe-style fine edge blade, this folder is engineered for heavy-duty cutting and prying. The Fullback AO features Gerber's F.A.S.T. 2.0 assisted-opening mechanism, and contains a secondary lock to ensure the blade stays closed during storage and transport. The knife features a textured glass-filled nylon handle. A lanyard hole accommodates various carry options.
