the cable knife AV3820 enables a precise, fast and safe stripping of all common round cables with a diameter between four and 28 millimeters. With the aid of an adjusting wheel in the housing, the cutting depth of the cutting blade can be infinitely adjusted. This prevents damage to the inner conductor. The cutting blade is self-rotating integrated in the housing and thus enables automatic conversion from round to longitudinal cut. In addition, a hook blade was integrated into the AV3820, which can be recessed in the housing. In both positions the blade can be locked. This leads to a significant reduction in the risk of injury, which can bring fixed blades with it.
