Black arrows were smithed by the dwarves who were the best smiths in all of Middle Earth. They create the best weapons and armor such that even the elves want it. It was probably made of a mithril alloy that was super rare meaning that only a few were able to be made. Also, Erebor and Dale were totally tight, One not being able to function without the other. Plus having Sick archery skills and knowing Dragons come from the Withered Heath in the North I would give all my Black arrows to the men of Dale.
