It’s really clever and incredibly well designed but I don’t know how well it would work for anything other than GEM style blades. The instructions call for keeping the leather clean and even say to rub in lather “often”. I’m just now learning they made and sold a razor to go with the stropper AND they sold them in a set! I think if you find one in your collectors price range get it BUT only if it’s in the condition you want, they aren’t easy to restore so don’t think you are going to buy cheap and fix. You can get them really cheap if you are patient. I know I had a second one at one point (maybe made by another company) but can’t find it.
