Or are they can openers? Ours can't anymore – the cutting parts are still sharp but one of the plastic handles has cracked in such a way that it's no longer possible to squeeze them shut sufficiently tightly. So in the grand tradition, I turn to a cycling forum for kitchen item recommendations. In the equally grand tradition, I might then ignore you all and get whatever's cheapest at Argos or Wilko! But it's still fun and interesting to get the opinions. The broken one, for what it's worth, was a Culinare MagiCan, a present from my mum more than 15 years ago.
