Bone Crusher

Bone Crusher was an ivory sword utilized by Senmaro, a Kaguya lord of the Warring States Period. A large sword, it is known for its (as the name suggests) ability to crush bones with every swing. Due to its large size, it is taxing to use for most, unless someone is extremely fit and muscular, or uses jutsu to assist them in its wielding.

This sword can also be used with nature transformations, as seen when Tabin uncovered the sword and took it for his own, and uses it for his Wind Release. It is also possible that Senmaro used Earth Release through Bone Crusher as well.

With this sword, Senmaro was able to take down lots of shinobi with simple swings, and very powerful weapon, in the right hands.
