Why not make it so if you repair your items it shows each part your repairing and raw material can aid to the process rather than alot of raw material being worthless. (a bit ambitious i know) But it would add an RPG element into it right? or atleast when you give your item back to the blacksmith he's like ohhh..... I can fix this *grins*. And then repairs the scratches and dents and makes it shinyyyy brand new again rather than my iron sword after being equipped for a year stays exactly the same regardless of whether i'm swinging it around on the beach or in the middle of the sea..
