Stone daggers. Simple enough. 3.0 melee damage, 150% attack speed, 75% reach. Would be made by 1 cobblestone and 1 stick in a regular dagger recipe. Maybe the stone sword recipe would be removed and stone daggers would replace stone swords, because a stone knife is much more realisic and logical than a big sword made of stone. They would also be a good starter weapon for people who like fighting with daggers, or if anything, a cheaper tool to cut kebab with. Stone daggers would also be wielded by Rhudaur hillmen, Dunlendings and maybe Moredain.
The texture I made is highly based on a normal stone sword and it might not look very great, because my skill in making textures is similiar to my skill of making usernames. Bigger version of the texture was given by User:Rayn Turammarth.
