TConstruct Hammer Heads Have Wrong Mining Levels

Nettehlol claims:

TConstruct hammer heads have wrong mining level values, f.i. Bronze shows as "redstone", but creating a full hammer with Bronze Hammer Head ends up as "Tin" level.

Ugh... I can't figure out why the hammer head and pickaxe head work differently in this regard. Hammer head shows mining level if it were boosted, pickaxe head shows mining level before being boosted. But the completed tool shows the correct stats in both cases.

Maybe I'll just punt, get a minimal repro, and report it on the Iguana Tweaks repo.
