Whetstone (device)

Whetstone (device) is a members item. No shop sells Whetstone (device) and no monster drops it, so an Ironman makes it: it takes 100 Invention and gives 300 Invention XP, using Hammer, 5 × Base parts and 5 × Deflecting parts.

“Used to repair items which are in a degraded or broken state.”

Ironman verdict

Where the materials come from: Hammer (sold by Drogo's Mining Emporium for 13 coins). Making ten takes 10 × Hammer, 50 × Base parts and 50 × Deflecting parts and gives 3,000 Invention XP. Reaching level 100 Invention takes 14,391,160 XP in total; the Invention calculator counts the actions and materials to any target, and the Invention guide has the Ironman training route. Whetstone (device) is members-only. It is tradeable on normal accounts, but an Ironman cannot use the Grand Exchange or trade for it, so the sources on this page are the whole list.
