A favorite of Kokukozus, his Twin-Headed Kunai is merely two kunai smelted together at the side-tips and wrapped together, in bandages, by their handles, both in opposite, diagonal directions; the heads facing away from each other. This is used very often by Kokukozu, and it seems they can come in three different forms.
- Twin-Headed Kunai - Simply the unmodified version.
- Chained Twin-Headed Kunai - This form of the kunai simply has a chain hanging from the holes at the bottom of them.
- Seal-Branched Twin-Headed Kunai - This form of the kunai has one large seal with several branching seals among it.
- In some places, this kunai has given Kokukozu the nickname "The Man With Two Heads".
