Remember Super Gillette double sided razor blades. Boy! they were good. For example. A female magician used them for her grand finale'. She swallowed a length of twine and then swallowed a dozen Super Gillette blades. Then she used to pull out the twine with all twelve blades attached. One night, only eleven blades were attached and she ended up giving herself an appendectomy, a hysterectomy and succeeded in, circumcising her husband, castrating her lover, gave the vicar a hare lip and... she still got three good leg shaves when it finally showed up.
