The ergonomically shaped plastic housing makes the snap-off blade knife comfortable to hold. The solid metal guide offers you safe and controlled cutting through cardboard, paper and film. The integrated blade magazine is equipped with a spare blade that you can change without tools. The blade is compatible with standard 18 mm snap-off blades, which can be retracted and extended using the slider with autolock function. You can use the removable cap to safely break off blunt blade segments and change blades.
