Hattori's Katana is a meleeweapon which has a special charge attack that will be activated if the attack button is held down after an attack. The charged attack deals critical damage.
"All uncharged attacks deflect bullets (but not grenades)."
Notes[]
The fourth attack shown in the details section of this page represents the charged attack, however, the charged attack can be initiated at any point in the combo.
When striking the back of a Thorny, the player is not always injured. The charged attack enables the player to bypass the protection provided by their back and deal damage without injury.
The damage from the charge attack comes directly from where you stop moving, meaning that if a Shieldbearer is facing you when you start the charge, it will damage the Shieldbearer once you finish. This works the same way for every other enemy that can block attacks.
It in particular is named after Hattori Hanzō, the sword-smith who created the weapon.
This weapon was added due to high popular demand for a katana weapon, similarly to the Vorpan and the Scythe Claw.
Holding 2 of this weapon with a legendary and normal version will let you do 2 consecutive crit dashes with the right timing, with the second attack traveling a bit less far. The timing is precise and you must hold the other attack button immediately after the red slash at the end to execute the second consecutive crit dash.
Because of the large vertical range on the charged slash it is possible to kill Kamikazes and other enemies that hang on the ceiling through thin floors and platforms.
