I have a couple Hart Steel razors and as far as shaving goes I like them both. I am lucky enough to have two with good quality ( it took sending one back but the replacement was fine) The problem I have with one of them ( the 7/8) is it will not stay tight. In the process of moving the blade in the scales for the different shaving positions it comes loose and I have to stop and tighten it. Just wondering of any of you Hart folks have solved this problem. I was thinking of a tiny lock washer??
