The NUMBER ONE USE for +60 hammers, if you only have one, is and should almost always be ENHANCING smith items when not using a forged metal tool.
About 15 years ago, there was a +1% bonus to enhancing success for every 10 points of Blacksmithing* over 100. Therefore, there's a 6% higher chance enhancing with an ASH+60 compared to without one, if enhancing with a GM, Elder or Legendary Smith. (which may explain a couple items over the years I accidentally SUCEEDED in enhancing when I targeted them without using a forged metal tool first, that SHOULD have been 100% chance of failure).
Repair deeds and actual repairs are good uses, but one has to be willing to churn the Blacksmith points to get them. I'm still using the ASH +30s from an IDOC 10 years ago for those.
And, you can craft anything that doesn't require a recipe 100% exceptional with a good smith talisman and a +30 ASH.
*(and presumably Tailoring as well - but a lot of people are wary of anything Tailoring, after they NEVER DOCUMENTED that Tailor BODs were 1/3 exceptional chance instead of 1/2 like Smithing and every skill with exceptional BODs after Tailoring - and only admitted it around 2007-8 after we confronted them with accumulated data we'd collected, and I think some of them were shocked to find that there was no documentation online other than a 2000 uo.com post that said Tailor BODs would work like smith BODs, which led to everyone expecting the 50/50 chance of smith BODs)
