Sabi Sabi no Mi

The Sabi Sabi no Mi, also known as the Beri Beri Fruit, is a Paramecia type Devil Fruit that allows the user to cause metallic items to rust and come apart. "Sabi" means rust. It was eaten by Shuu.

Strengths and Weaknesses
The only strength of the fruit, so far seen, is that the user is able to rust and pull apart metallic weapons such as swords. Doing so apparently gives the user somewhat of an advantage against sword weilding opponents. The fruit so far doesn't seem to have any specific weaknesses outside the standard Devil Fruit weaknesses

Usage
The fruit's bestowed powers, as used by Shuu, have so far been used for defensive purposes, if not offensive purposes. Shuu has used the powers of the fruit to rust the Yubashiri of Zoro after catching it in his bare hands. He was then able to pull apart the sword as if the sword was nothing.
