Rusty item

Rusty items are a small class of items introduced in The Lost Age. They are unique weapons that are extremely weak when first found, but if you have Sunshine the blacksmith in Yallam take a look at a rusty item he will offer to reforge it. If you do, he will take it, and you should leave and reenter the town so that he will be done reforging it into the rare weapon artifact it's meant to be, for a price of course (though in the English version of the game the price is not stated).
