What is your suggestion?: Adding the ability to smith each pickaxe.
Is this in OSRS?: No, and why would that matter?
Has this suggestion been accepted already?: No or it'd be in the game already.
How would this benefit Alora?: Ironmen (or any similar mode) would greatly benefit the simple action of being able to smith our own pickaxe considering that tool is what you need to train both mining / smithing anyways.
