99octane

Thank you everybody. Yes, I thought about peening some steel wire in there. Unfortunately it runs parallel to the edge, at about an inch from the edge itself, so I had my doubts about it. It's very shallow, though.
I'll take a picture this evening.

Anvil, thanks for the link, I read it but it looks like it concerns much bigger restoration work than what I have here.
 

Hi everybody. After a few years, I finally did it: got really dumb and left a 1mm wide, 0.5mm deep, 15 cm long furrow in my anvil's face with my plasma cutter.
Even if it's fairly small, and not really in the way of where I usually forge on the anvil's face, I really do not want to leave it there. 
It's a 50 kg, italian pattern cast steel anvil in pristine conditions under any other aspect. 
How can I repair it? Any help is appreciated.
