Who got the strongest throwing power in NV?

[Sugiyama]

No, I'm talking about Throwing power like Throwing a Kunai to the point it can pierce Tree or solid construct.

It was Assuma who threw the kunai that pierced the tree and said that had he focused more power in it it would have pierced even the rock behind it.

Madara. I saw him kill somebody with a kunai.
