Notes
Part of the Akuma Slayer set.

Compared to other katana, the Kazekiri has a reduced fire rate, a slightly shorter range, and does less damage per shot than the majority of other top-tier katana. However, it makes up with it with a second shot. Its shots curve outwards before curving inwards again, which is usually not significant enough to make its shots miss.

Compared to the other top-tier katana options, assuming it lands both shots, it outdamages the Masamune until about 58 DEF, the Sadamune until about 10 DEF, and the Doku no Ken until about 66 DEF.

Also worth noting is that weapon has the rare trait of piercing obstacles along with enemies. This can prove useful in areas that have a lot of obstacles in the way, or if one needs to take cover behind obstacles while continuing to fire at enemies.

When the entire Akuma Slayer Set is equipped, the weapon projectile changes to:
Katana Akuma Slash Big

History
Before Patch X.33.1.0 (May 2020), this item had a Feed Power of 500.

Trivia
Its name roughly translates to Wind Shear/Cutter (風切) in Japanese.

The odd capitalisation used in the description is indeed how it is written in-game.
