I have six NOS filarmonicas (yep, 6) and love every one of them.. But I do believe that the real reason for this love is feeling that they are NEW. Nobody shaved with them before you, and they are amazing quality..
Combination of this 2 reasons give you what you hardly can get today – outstanding old steel and new razor. Of course you can get new razor any time.. but nothing can compare with OLD and NEW razor at the same time :)
