It doesn’t look very pretty. It doesn’t smell great. It isn’t a cute colour or soft to the touch – in fact, you could be forgiven for thinking it’s a missing part from some unidentified piece of flat-packed furniture. So why am I telling you about it? Because it works. And what is it? The Razor Pit. And though you may not know it yet, you need it. What does it do? It’s a razor-reviver, re-sharpening your flagging razor and saving you a few quid (and the tiresome hassle of buying new blades) for a little longer. It’s easy to use – you just run the tired old blade back and forth over the flat rubber surface of the device and voila, a razor re-born and another close shave.
