Well this is the type that the heel is welded on as a entirely seperate peice. If the weld wasnt good or it was really really cold out it could break off really pretty easily. There was another smaller anvil there with the horn broke off i thought maybe he had $60 on it but he had $100 so i just kept walking. Horns can get broken off if you are really abusing it. Using the horn for really heavy fullering a lot ,for example, can really tear up an anvil pretty quick.
