Hi all, there seem to be a lot of people using SE razors. This has me intrigued. Should I be looking for a vintage Gem type or Schick type injectors: they seem to be cheap enough on-line but I would not know what to look out for other than buying from one of the reputable stores. Or should I be looking at one of the modern ones like the Supply Single edge razor, or One Blade made in USA. Any tips would be appreciated, TIA. Chris.
