I want to make a fighter that focuses on being the ultimate blacksmith / magical item crafter, but I have very little knowledge / experience of crafting. Is this possible for a non-caster and if so, what will I need to be able to accomplish it?
You are looking for Master Craftsman from Core Rulebook

A Blacksmith would need Master Craftsman and Craft Magic Armor/Weapon
