For as long as I can remember the soft iron rivets were black. This year, when my order came in, they were zinc plated. I called the supplier and he said they were the same only plated. My students seem to be having more trouble peening them. I tried a few and they do seem harder to me. I reordered some black ones. Are the plated ones harder or is just my imagination? Thanks, Ron
