CobraTec Knives Viper Features The Cobratec Viper Automatic Folder uses a D2 tool steel blade a material prized for its hardness and edge retention well beyond typical stainless knife steels. The satin finish on the 3.125 inch blade reduces glare while giving the knife a polished clean appearance suited to everyday carry. A hidden release mechanism allows the blade to deploy quickly and discreetly without a visible actuation button interrupting the knife s clean lines. This design keeps the Viper s profile sleek while still delivering the fast one-handed deployment automatic knife users expect. The OD Green aluminum handle gives the Viper a durable lightweight grip with a tactical color option that stands apart from more common black or silver finishes. At 7.37 inches open and 4.25 inches closed the knife offers a substantial blade length while still folding down to a pocket-friendly size. The combination of an aluminum handle and D2 steel blade keeps the overall weight manageable for all-day carry. Everyday carry users looking for a fast-deploying automatic knife in a distinctive OD Green finish will find the Cobratec Viper a strong choice.
