There are many crafted weapon exlpoits but ill talk about the most efficient wich is Javlins with teh harpoon head they sell for 106666 gold each without teh sell price perk in addition to this they will rapidly level up your charactors balcksmithing skills. but the biggest part of this exploit is that you can use them while bartering with lords(assuming that the lord is not in a settlement) this results in being able to easily buy peace, take all of a kings money, make lords defect, make lords like you and anything else taht can be gained from bartering.
