The iron Forgath had been able to call and refine through his dark arts had been enough for many simple tools; picks, shovels, tongs, mallets, wedges, an anvil - the various sundries one would need to dig, mine, or forge.  They were basic and temporary, the touch of his magic not enough to refine and temper better alloys, but steel would come in time.  His magic did nothing to make them comfortable to wield, so ponies took to wrapping bits of cloth around the shafts in place of proper handles.  Still, it was a start.
