Yesterday I put a Bolzano SI blade in my 1940´s Matador razor and I must say the result was astonishing! I face lathered with (euro) Palmolive Classic cream and followed with some cheapo Gillette AS gel as I forgot my Proraso cream and *** at a relatives place when on vacation. Being forced to use other stuff for a while is an interesting experience, especially since my first shave without my normal stuff was actually better! Might be all due to the blade though. Definitely the best blade for me so far rivaled only by Astra SP. Will have to compare them more thoroughly over an extended period of time using various creams.
