Introducing  CobraTec Viper Hidden Release automatic. This knife doesn't open like most folders, but you'll know the secret to its smooth automatic action. The Viper Hidden Release utilizes a hidden bolster release; a simple, deliberate slide of the bolster from the front to back, deploys the blade and also unlocks it. You will soon determine that with its unique opening operation and svelte design, it is a capable EDC option and a part of your collection you'll be excited to show off.   

This blade is made of D2 steel and must be kept clean, dry and lubricated when not in use to offer you a lifetime of use.


All CobraTec OTF knives are backed by a LIFETIME WARRANTY.
