Viper Free V4892GR D2 stonewashed, green G10

The Viper Free is a stylish pocket knife with a deceptively simple appearance. This sleek designed pocket knife has an ingenious locking mechanism; the Smart Lock system developed by Viper. At first glance, it is not very different from an ordinary liner-lock. In short, the difference is that an ordinary liner-lock actually locks against a partially sloped side. With the Smart Lock , the locking bar falls hollowed out part especially made to fit. The slider on the back of the handle helps you to adjust the tension on the liner.
