e Inverted Spear of Heaven is a dagger with a jitte-shaped blade. It has a q shaped circular hand guard that points out on the side of the longer blade. Additionally, the weapon has a black handle with a circular link at the end that allows it to be connected to metal chains. It appears a third blade may have been located on the front of the weapon but it has evidently been broken off.

It has been imbued with a cursed technique powered by a special foreign type of cursed energy that allows it to force the stoppage of any other technique it comes into contact with. If a user's target or their jujutsu is hit by the Inverted Spear of Heaven, it will be immediately nullified. Even powerful cursed techniques like the Limitless can be completely stopped by this weapon.
