If I am understanding this correctly, the question is should we restore razors or leave them be ???

First there are two types of razor collectors out there.

The first group, most of us here at SRP, and the other shaving forums, are shavers first and foremost, and collectors second..
So our blades must be free of any active rust etc: or they could actually be dangerous to use in our pastime... So I would say yes to most restoration... Taking it as far as each owner deems they would like to... Personally I want clean, bright, shiny, steel on my face....

The other group of collectors out there are mostly after the vintage scales and razors, so they would look at restoration as a bad thing, because they want to keep the razor as original as posible...

Two totally different points of view on the same subject matter...
