Viper Dan 2 5930BC Bocote N690, sheepfoot

The Viper Dan 2 is a stylish friction folder with a deep-carry pocket clip. A friction folder is a pocket knife without a real lock. However, you can feel some resistance on the blade, which means that it won't just snap shut. You can open the knife easily with the front flipper. When opened, the flipper sits neatly on the back of the blade, exactly where you would keep your thumb. By pushing your thumb down, you keep the knife open while you use it. Friction folders are popular because they can be legally carried with you in the United Kingdom and Germany, among other places. Plus, it is of course a magnificent mechanism, which is appreciated by many knife enthusiasts.
