The Supreme Whetstone is a Material Resource used in upgrading weapons from level 8-9 by crafting Mighty Jewels and the other elemental jewel. Its finite recipe, made from Supreme Quartzite Shards, can be unlocked after finding the Stump BURG.L Chip and buying the recipe for Mighty Jewels, but its renewable recipe is locked fairly late in the game by retrieving the Ominent Data Disk from defeating Director Schmector.
