The CobraTec Viper brings stealthy innovation to your EDC rotation. Featuring a hidden bolster release, this automatic knife opens and closes with a deliberate slide of the handle - no visible button needed. The 3.125" black titanium-coated D2 steel blade offers excellent edge retention and durability, while the slim 4.25" aluminum handle ensures a sleek carry. With its unique mechanism and svelte design, the Viper is as functional as it is fun to show off.
