Started out with Astra greens then jumped all the way up to feather and Gillette Nacet, and then a whole bunch of others. Once I popped these into my Henson medium or my Rockwell 6 c with a number four plate I never looked back. Hands down they're less aggressive then Nacet and very sharp. I used to do three passes and now I only do two because it just gets done. With sensitive skin it works just fine as long as I don't go against the grain where frankly any sharp razor starts irritating the skin.
