After years of using standard ones that are difficult to turn, don't cut properly and are basically rubbish, I happened to borrow one at work that seemed incredibly easy to use. I ordered the same one for home a few months ago and it still works like a dream, cuts the can like butter it's so easy, but looks like any other manual can opener. It's made by Brabantia ('tasty+ can and bottle opener'), I ordered it from their website and it cost £9.95 plus tax and delivery. Highly recommend, and I don't work for Brabantia and wouldn't buy one of their over-priced bins! I imagine it would be especially good for people with reduced strength in their hands.
