This little gadget hones your razor after each use, and extends its usefulness by keeping it sharp longer. It’s a strip of silicone rubber in a plastic holder. You push your razor along the strip a dozen or so times after you’ve shaved. I’ve used it for about two years and it works well – it gives me at least double or perhaps triple the number of shaves before the blade becomes too dull to use. I’ve tried other similar things but this is the one that works best. — Stephen Saxe
