CobraTec Knives Viper 3.12" OD Green Automatic Folder D2 Black Blade

The CobraTec Viper is a hidden-release automatic folding knife built around a 3.125" D2 tool steel blade finished with a black titanium coating that resists corrosion and keeps a low-reflective working edge. The concealed bolster release snaps the blade out the side with authority, then locks the D2 blade up solidly for everyday carry or tactical use.

The chassis is machined from high-grade aluminum alloy and finished in OD Green, measuring 4.25" closed and 7.375" open at a carry-friendly 4.0 oz. The aluminum build keeps the Viper light on the belt while remaining rigid in the hand, and the hidden-release mechanism gives it a clean, low-profile silhouette free of protruding switches. Backed by CobraTec's lifetime warranty, the Viper is purpose-built for users who want an automatic folder with a discreet deployment and a rugged D2 working edge.
