... especially made for extended cutting depth up to 40 mm (e.g. Styrofoam). The spring-loaded blade retracts automatically as soon as it is no longer in contact with the material to be cut, thus ensuring greater safety when cutting (do not hold the slider while cutting). TÜV and GS tested. The metal body with rubberized grip zone comfortably fits perfectly into the hand. The blade is ambidextrous and easy to reposition. A large safety eyelet is available.
