Let's try this again...
I hit the wrong button, and somebody read this before I could edit it...sigh...
So, over the years, I've purchased a few fixed
blade knives 100 years old, +/-...
The blades are in good condition. Not eBay "mint".., but pretty good.
They seem to have been dipped in some sort of "varnish" to protect the carbon steel. It seems
to have worked well.
What is it?
