Sazanami

Sazanami (漣, Sazanami) is a special blade created and solely used by Heiwa Uchiha. This blade, unlike conventional swords, is not made of any metal. However, it is still regarded as one of the most versatile and, oddly, durable blades in existence. It is usually utilized by Heiwa to, commically, keep his Samehada in check.

Appearance
The blade itself is merely a hilt, made of carbon-fibre reinforced polymere, with rubber surrounding it. The rest of the blade does not exist, and it is formed by special water kept within an opening in the hilt, which solidifies into an extremely thick blade, capable of cutting refined steel like a hot knife through butter. This water usually grants the blade transparency or turns it blue in color, former of which is useful for stealth. The water retracts at the user's will, allowing it to be portable without the need to be kept in a scabbard or a scroll. The blade is also a symbol of Heiwa, as it shows his true love for the village.

Abilities
In addition to it's immense and peculiar level of durability, the blade has a special ability. When a person is cut by the blade, they are forever trapped in an illusion incapable of being released, thus bearing resemblence to the legendary blade of Totsuka. This illusion can only be released by a user performing a sacred sequence of handseals, which is only known to Heiwa himself. Additionally, due to the blade encompassing his very own persona, it can only be wielded by him, as the water only retracts at the hands of someone else.
