I have read on the forums that German, French and some older American blades are made of good quality steel - but to stay away from some of the Czech stuff (might have been elsewhere) My question is this: What makes a blade "good". How do you know its a good blade if it isnt from Dubl Duck, Thiers, Dovo... ect. I just bought a new razor and how will I know if its not a piece of crap?
