So I expressed an interest in learning to shave with a straight razor to my wife the other day. She told me that her dad had been a barber, and she still had several old straight razors of his that I could look into. So I'd like some help identifying if any of these razors are good quality, and anything that I could perhaps still use. The man passed away in (I believe) 1977, so they all should be older than that, but other that that I have no idea of what year he would have been using them.

Here are the pics:

So the one of the top says Vita Style on the handle, and 121 NU-VITA on one side of the blade, with "Made in France" on the other side
The middle one says Edmond Roffler on both the handle and blade, and "Made in France" on the other side of the blade
The bottom one just seems to say "Tondeo" on the blade. It's the only marking I can find on that one. Any insights and advice would be greatly appreciated! Thanks!
