That makes since. Here’s a picture after I wire wheeled that side. I just don’t see anything that resembles a stamp. So after I wire wheel the anvil, what do you recommend I put on it for protection from rust? Are these holes at the bottom from a blacksmith testing his tools after heat treatment? So what exactly is is anvil made of? I don’t really see a peace of carbon steel welded on top. Sorry I’m knew at this and very interested, I think it so cool. One last thing, I believe someone used the anvil to rest what they were welding on top of the workrest. There are a couple holes that look like they burned the carbon steel that is on top. Since I will be using this anvil in the future for forging knives, should I feel those holes up with welds and grind them flat?
