50 lb cast iron anvil no longer sold at H F Tools seems to do fine when placed at the right height. Nice and quiet thump thump. Will probably duct tape white some cutting board to its surface for punching holes.
I'm saving and using my sale priced $25 w00d r!ver black granite surface plate for its intended use sharpening items such as wood working chisels and leather tools. Just use black wet dry carborundum sandpaper for an instant whenstone.
