Bronze arrow heads can be obtained from Smithing a Bronze bar on an anvil at level 5 Smithing. One bar produces ten arrow heads, and gives 12.5 smithing experience. With a level of 1 Fletching they can be attached on Headless Arrows, to gain 15 Fletching experience and Bronze arrows.
Bronze arrow heads are the only type of arrow heads that are priced equally with all the other shops. Iron arrow heads and up are sold for a higher price at King Lathas' Weaponry Shop, normally making it the most expensive option.
