*takes the dagger and inspects it* You know that kunai can be very versatile, here I made this for you. *gives a tiny wooden box* Inside is a mod that will allow the kunai to burn forever, I heard somebody call it "greek fire," I had another name for it, but I like greek fire as its name. Oh and the box is fire proof, just attach the mod to the holster of the kunai and it will spread to each one thrown.
