The WEICON cable knives allow for precise, fast, and safe stripping of all common round cables. The product family of cable knives includes various types, each equipped with different additional functions to meet the individual needs of users. The cable knife S 4-28 enables precise, fast, and safe stripping of all common round cables with a diameter between 4 and 28 millimeters. With the help of an adjustment wheel in the housing, the cutting depth of the blade can be continuously regulated. This prevents damage to the inner conductors. The cutting blade is self-rotating and integrated into the housing, allowing for automatic switching from round to longitudinal cuts. Additionally, a hook blade has been integrated into the S 4-28, which can be retracted into the housing. In both positions, the blade can be locked, significantly reducing the risk of injury associated with fixed blades.
