I tried to create a sword. I had the required 4 pieces of iron and a smithies hammer, and I had activated an anvil.
However a message came up saying I needed an anvil to craft a sword
Either the anvil I'm attempting to use is bugged, or I don't have a skill and the message is wrong.
In further testing, I had the wanderer try to make it and he couldn't, and then I tried making a miners helm and couldn't do that either.
I have previously used the anvil to create plate mail armor, so I know how to do it and it did work previously. I do have the swordsman skill
