Deteriming Razor Composition
Is there a way to determine my straight razor's metal type? Currently I have two vintage razors: One is my great-grandfather's that, after doing some investigation, found it was bought from a cheap source. That isn't a knock on my great-grandparents. They were farmers and pretty economical. The second is a flea-market find and seems to be from 1910-20ish time frame. At least that's what I've determined from investigating the internet.
I'm a decent honer, but I'm wondering how I can determine if the razor is stainless or carbon steel. I'm pretty sure the first one is carbon but the second on...not too sure. Is there at test I can perform?
Thanks in advance.
