Ame-no-Habakiri

Ame-no-Habakiri (天羽々斬, Heavenly Wing Slash) is the name of an exceptional tanto bequethed to Toshishiro Katashima by his father, Homusubi upon his passing. During his time as a member of the ANBU-subdivision, Homusubi wielded this specialized despite the fact that it did not conform to what was defined as "standard" for the organization's armaments. Aesthetically, it clashed with the tip-less tantōs wielded by his fellow operatives, but this difference paled in comparison to the ability housed within its seemingly-humble form. When is flowed throughout its length, Ame-no-Habakiri responds with the spontaneous manifestation of an azure-hued aura. Then, with but a rudimentary slash, this aura is launched in a crescent-shaped arc that is seemingly-razor sharp. However, upon contact with organic and inorganic materials, it is soon revealed that there is no visible damage whatsoever. This is because the chakra-composed crescent does not affect physical matter in any way...but wreaks havoc upon the of living beings. For example, "cutting off" an opponent's arm through usage of this form of attack would result in the literal loss of ability to utilize that arm in the formation of ninjutsu; for the making up the limb are effectively shut down. What's more, the sensation of losing a host of tenketsu is one synonymous with the word agony. Of course, through proper medical treatment, the damage caused by Ame-no-Habakiri can be reversed.
