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 the same as darts. Along with bronze knives  which are the same range bonus as iron darts, are considered to be one of the fastest and most efficient ways to gain  Ranged   experience.
