A SafeCut blade that keeps fingers out of harm's way
On the Proton A4/120 the blade is enclosed in a SafeCut cartridge and cannot be reached when the trimmer is idle, which makes it safer to keep on a shared office desk. The paper clamp holds the sheets still while you cut, and the printed guides help line up documents of different sizes. The housing also has built-in storage for SafeCut cartridges, so spare blades stay with the trimmer.
