Iron arrow heads can be obtained from smithing an Iron bar on an anvil at level 20 smithing. One bar produces ten arrow heads, and gives 25 smithing experience. They can be used on Headless Arrows, to gain 25 Fletching experience and Iron Arrows. They can be bought from either Gulluck and Sons in the Grand Tree, King Lathas' Weaponry Shop, or from Hickton's Archery Store in Catherby.
