I have been using this 60kg anvil for almost a year now and it is awesome, it has around an 80% rebound and is as hard as advertised. The horn is not hardened, just the working face. It has withstood many thousands of hammer blows with hammers up to 20lbs. The only minor complaints that I have are mostly that the hardy hole is an oddly large size and the pritchel hole is all but useless, but for the money it can not be beaten.
