On MÜHLE safety razors, the blades slightly protrude on both short ends of the razor head and customers keep asking if this is meant to be and whether they can cut themselves with the protruding edges. Our answer is: yes, the blade is supposed to protrude and no, one cannot cut themselves as the edges are blunt. The protruding blade helps indicate that it has been inserted into the razor. Also, it is easier to grab here when changing the blades - no need to touch the cutting edge. When changing the blades, the safety razor should be facing downwards and be laid onto the table head first. In the next step, remove the handle, take off the lower part of the razor head, grab the blade with both thumb and index finger at the protruding end, then remove it and insert a new one.
