With the striking and clear color coding, you can quickly find the desired profile and avoid tedious searching. The blade clicks into the VDE handle with an audible and tactile confirmation and is easy to replace. You do not need a handle for each profile, saving space and weight compared to conventional screwdrivers. The elastomer coating over the slim polypropylene handle is non-slip and pleasantly skin-friendly. Super slim in the front third, you can effortlessly reach deep-set screws with the slim blades. Each individual blade is tested for you in a water bath, piece by piece for your safety. In the quick rotation zone with your thumb and index finger, you can safely use the individual blade without a handle thanks to the anti-slip protection.
