As the blade is made up of scales, it inflicts injuries through shredding or shaving what it comes into contact with, rather than just cutting the object in question. This flaying effect is similar to a shark's skin, hence the sword's name. While it ordinarily remains rigid, Samehada's hilt is able to stretch and bend to great extent, allowing the weapon to be used like a flail.[5]
Samehada shares a symbiotic relationship with its wielder, similar to that of the kikaichū. Although it continually consumes the chakra of its owner, its largest meals come from fights, wherein it absorbs the chakra of the opposition instead.
Such an ability allows Samehada to literally slice through an opponent's techniques, in spite of whether the chakra has been transformed or not,[6]
and even prevent them from being performed by absorbing all of the necessary chakra, before preparations can be completed.[7][8] This is particularly useful when fighting jinchūriki, as Samehada can quickly deplete their large chakra supplies as well as remove their chakra cloaks, illustrated when Killer B was reduced back to Version 1 after initially being in Version 2.[9] However, it seems to be unable to automatically absorb ambient chakra, as in all instances where it has absorbed chakra are when either the opponent had a visible aura around them or when direct physical contact had already been established.[7][8] Due to its voracious appetite, Samehada is drawn to those with large chakra supplies, allowing it to be used as a quasi-sensor.

Tsukuyomi is thrown out too since this page says it continually takes chakra from Kisame.
