Product Description
The Benchmade AFO II 9051SBK is a full-size automatic folder built for law enforcement and military personnel who need fast, reliable single-hand deployment — a 3.56-inch 154CM blade in a black aluminum handle with a push-button mechanism designed to deploy and close under duty conditions.
The blade is 154CM stainless with a black coating and combo edge. 154CM is a proven, easy-to-maintain workhorse alloy — it holds a serviceable working edge and sharpens without difficulty, appropriate for a duty folder that needs regular maintenance in the field. The black coating reduces reflectivity for low-visibility carry. The combo edge runs plain toward the tip for general cutting and serrated near the handle for seat belts, cord, and synthetic materials that resist a plain edge under pressure. The aluminum handle keeps the package at 5.40 oz while providing a rigid, corrosion-resistant chassis. Push-button deployment is fast and repeatable; the liner lock secures the blade open.
Note: Automatic knives are restricted or prohibited in some states. Verify your local laws before purchasing. Ships same or next business day from Knifeworks in Columbia, Louisiana.
