Space-Time Kunai

The Space-Time Kunai are special daggars utilized by Uematsu in conjunction with his Jikūkan Ninjutsu: the Flying Thunder God Technique and its alterations. They differ in look from a standard kunai by having three blades instead of one and on the handle (which is thicker than normal) is the "marker" for Tomi's teleportation ability; Tomi also said that it's a bit heavier than a normal kunai. The prongs on them also makes more deadly in melee fighting. He seems to prefer using these special daggars over the standard type.

After some time, this class of daggar was altered to be more sturdy in the face of heat and pressure, able to keep their shape in most conventional blazes as well as heavy explosions. It is still however possible to destroy them with advanced natures such as Blaze or Lava as well as to cut through them with Wind techniques.
