Kimimaro uses this jutsu to create a mass of razor-sharp bone spikes all over his body. These spines appear to be branches off his pre-existing skeletal structure rather than complete new bones. Kimimaro is even able to grow these bones at an extremely rapid rate so they can stab an opponent even as they are growing. He can even use them to block or trap an opponent's strikes. In addition to being an unwelcome surprise for opponents, it makes him basically untouchable at close range. If an opponent would start to get close to him, he would start to spin rapidly slashing the foe in multiple areas of their body.
