So after straight razor shaving for over a year, I inherited 4 straight razors from my girlfriend's grandfather (yay!). Two of them are in bad condition, 1 of them is a mustache razor I do not plan on using, but the last one seems great. There is some slight discoloration, especially around the metal near the pivot pin, scales, a few on the spine and a very few amount near the edge. I tried shaving some of the hair on my arm to have a quick and dirty shave-ready test and it appears to be good. I've done a lot by just reading things online but this I am having issues finding an answer to.

The new blade appears to be honed, so I was just planning on stropping it and shaving with it. I'm slightly concerned with how unsanitary it is though, since I do not know the history of this razor, and the fact that its been in a drawer in a basement for the last 50 years. I do not want to spend the money on getting it restored since there is very little to make it look better than it already does.

What needs to be done to an inherited straight razor to make it sanitary to use?

Does honing a blade make it sanitary to use?

Edit: I have a small amount of experience honing the two blades I had already purchased to shave ready condition (after making numerous newbie mistakes).
