Even easier blade replacement. Change the blade complete with the whole clip. Never take the blade out of the clip? Danger of injury! Use only the Credo-Safety-blades-clips made specially for this corn cutter. Even safer to us. Apply the corn cutter only to the dry foot and pull with light pressure. Never press or pull in the opposite direction. As a precaution we recommend people with diabetes or skin circulation disorders to consult their doctor before this treatment.
