The Dagger is a weapon introduced by the Weapons Master idea pack. It can either be thrown or used as a melee weapon. It can be crafted with 1 Stick and 1 of any tool-making material.
When right-clicked, the Dagger will be thrown. It will travel for about 10 blocks before falling to the ground. If it hits a mob, that mob will drop it upon death. If it misses the mob, it must be picked up in one minute or it will despawn.
