Popped one into my 1912 Gem SE and gave it a spin. Have to say they are as smooth or smoother shaving than any carbon steel SE blade that I have tried. Big bonus too is not having to deal with rusting carbon steel blades. I don't know why anyone would use carbon steel SE blades when these are available. If you live in Canada go the extra mile to import these, well worth it, imo.
