My Single Edge has today come back into use after a spell of DE's, Rocnel and Claymore razors.
Much as I like the razors that use Feather and Kai blades, it's a pleasure to be using an SE with a narrower, new blade. Even using a Personna blade, I managed a very satisfactory 2-pass shave, and I'm pleased that my initial good impressions of the Single Edge still stand.
I still think that, as an old butterfingers, I may end up needing a replacement screw and spring.
