Conventionally, you simply need to continue improving your smithing skills. There's also the enchanted "Notched Pickax" near the very top of the Throat of the World that can be disenchanted, thereby allowing you to make 2 more that can be dual-wielded, improving your Smithing 5 each.

Unconventionally, you can take advantage of the Fortify Restoration/Alchemy loop exploit to craft yourself potions and gear to make weapons/armor as awesome as you want it.
