Different from cursed objects, cursed tools are weapons infused with cursed energy. Due to this, even non-sorcerers can use them to combat cursed spirits.[1] Conventional weapons such as katanas can become semi-cursed tools over time if the user constantly imbues it with their cursed energy. However, weapons new to the user that are reinforced with cursed energy are not considered cursed tools.[2]
As with sorcerers and cursed spirits, cursed tools are categorized from grade one to four based on their power and potency. The higher the grade, the greater the advantage granted to the user in a jujutsu battle.[3]
Save for Playful Cloud, all special grade cursed tools are imbued with a cursed technique.[4] Additionally all cursed tools imbued with cursed techniques other than the Black Rope and the Sword of Extermination, are officially ranked special grade.[5]
Powerful cursed tools are extremely valuable. Their monetary worth can range from five hundred thousand to upwards of five hundred million yen.[6][7] All the cursed tools collected by the Big Three Sorcerer Families were stored in a vault called the cursed warehouse. Tokyo Jujutsu High's cursed warehouse is protected by Tengen's concealing barrier. Following the Shibuya Incident, the Zenin and Kamo clans reclaimed their respective weapons, emptying out the warehouse of cursed tools.[8]

Its full potential can only be utilized by someone capable of perceiving the souls of even inorganic matter.[14] Mai sacrificed her life to create an exact replica of this sword with the same abilities. It resembles a reed Mai gave to Maki and represents the last connection the sisters share. Maki first used this blade to take revenge for Mai by annihilating the Zenin clan[15][16] and equips it as her primary arm thereafter.
