Free Leopard

This is a two-step ninjustu that adds Kiban's chakra to his khanjar dagger by flowing his chakra through his weapon to the point it becomes visible. This increases the cutting power, range and resistance of his dagger, allowing him to use it more effectively. However, if the enemy is out of his range, Kiban may also hurl the dagger at him. Even if he misses, Kiban can then cause the chakra infused in the blade to become unstable and detonate it without warning. The explosion can leave quite a sizable crater in the aftermath and has been compared to that of a high-end landmine.
