Iron knife

Iron knives can be made using the Smithing skill at level 22. One iron bar creates 5 iron knives and grants 25 smithing experience. Buying iron bars and smithing them into knives is usually profitable depending on prices at the time. Like all knives they have an incredibly fast fire rate, so fast that, if used on rapid, 2 hit splats appear on the monster/person at one time. Along with bronze knives, these are considered to be one of the fastest and most efficient ways to gain Ranged experience.
