You should be able to equip bellows, hammer, tongs, etc. to your hands, then use them accordingly as you would any weapon. Just imagine the sheer, banausic thrill as unleash one last mighty hammer-swing to finish shaping that red-hot sword of slayage then dunk it in a bath of water. A cloud of steam shoots up, obscuring your vision momentarily before dissipating and...Ta-Da! You behold your beautiful neonatal blade in the grip of your tongs, wide-eyed and eager to be plunged headlong into deserving troll-bellies.
