First of all, welcome back.
I would suggest lowering AGI and DEX a little bit to get some VIT. IMO VIT is essential for leveling Blacksmiths, as they don't naturally have high flee even with Flee gears compared to Sins and Rogues. VIT is also needed for mobbing then using Cart Revo afterwards.
Ever since Renewal, I don't really know the point of using an Ice Pick anymore. The DEF nerf got to the point where a +5 Diligent Giant Axe on a Mastersmith does as much as a +4 Ice Pick with HSCR.
You could find leveling with Cart Revolution much easier than Mammoing in some places (like Harpies and Desert Wolves). Also, Cart Revo cannot miss, so that would be a huge advantage for leveling in the high levels.
Weaponry Research still does add Attack and Hit, although it doesn't show up in the status window like other Mastery skills.
Good luck
