If you regularly need to cut thick materials such as roofing felt, plasterboard, thick cardboard or strong foils, you are well equipped with the professional snap-off blade knife. With the ergonomically shaped metal housing, the knife sits comfortably in your hand and you can guide it through the material with maximum power transmission. Stability is further enhanced by the metal blade guide. This allows you to make precise, controlled cuts safely and with minimal fatigue. The integrated locking button locks the snap-off blade in the desired position, so it is always firmly in place without any room for movement in the guide and the risk of injury is minimised. The blades of this durable helper can be purchased and replaced without tools. One blade is included.
