Couldnt find anything on the anvil to give any clues, It does seem quiet when pounding hot steel on it, but I have nothing to compare to. I was hoping this anvil would turn me into a professional blacksmith, no such luck All in all I think I used the forge 6 times now... i'll have to try something other than tongs out of RR spikes, thats proving to be a little too advanced for me now... first thing I made of course was a knife, have no desire to do that again.
