Make iron spear have texture of pitchfork

When you will add spears to the game make iron spear have texture of pitchfork or add another craft with 2 iron for example that deals 1 aditional damage in compareson to just iron spear and will have texture of pitchfork. I know that there is trident in game but a villager with an iron pitchfork is the most danegerous entity in human history!
