I'm rinsing a razor in the sink, but it has a rather large 'head', the part with the blade. Somebody has suggested a certain way of washing it, involving tipping it under the water in a certain way. I haven't tried that before, so I do, and the head falls off and goes flying around the room in a most dangerous way. It seem like I was set up - it's not a way of washing it, it's a trick, and that always happens.
