Add rune bars to your metal bank. Use the anvil closest to the mines in Artisans' Workshop to smith rune knives. Each rune bar produces 25 rune knives. Profit per bar is 8700. The Artisans Workshop is used as it sits closest to the Rune ore and Luminite ore deposits in the Mining Guild for players that want to make their own bars for this method.
You can queue up multiple rune knives by right clicking the anvil and choosing "open smithing interface" and then choosing knives. Once your inventory is full you can start smithing them, when a bar is done you will automatically start smithing the next one.
