One Piece: Best Unconfirmed Grade Weapons Ranked

Shodai Kitetsu

The Shodai Kitetsu is widely believed to be one of the strongest swords in the One Piece world. Many fans think it belongs to the highest sword grade, but its exact rank remains unconfirmed. Wielded by a powerful figure, the blade carries the fearsome Kitetsu name and remains wrapped in mystery.

Gryphon

Gryphon, the sword used by the legendary pirate Shanks, has never received an official grade. Despite this, its incredible feats in battle suggest it belongs among the finest weapons ever forged. Gryphon has clashed with top-tier opponents, making many fans believe it could be a Supreme Grade sword.

Ace

Not to be confused with the pirate of the same name, Ace is the saber carried by Gol D. Roger. The Pirate King's weapon played a role in some of history's greatest battles. Since its grade has never been revealed, speculation continues that Ace could rank among the strongest swords ever created.

Murakumogiri

Murakumogiri is the massive naginata wielded by Edward Newgate, better known as Whitebeard. While its exact classification remains unclear, the weapon's reputation is unmatched. It was used by one of the world's strongest pirates and is powerful enough to be considered among the highest-grade weapons.

Napoleon

Napoleon is a unique weapon because it is both a sword and a living Homie. Used by Charlotte Linlin, the blade has displayed remarkable versatility and power. Its unusual nature makes grading difficult, but many fans believe its strengths place it among the elite weapons in the series.

Raiu

Raiu is the sword carried by Shiryu, one of the most dangerous members of the Blackbeard Pirates. The weapon has never been officially ranked, yet its owner's reputation and combat ability suggest Raiu is far stronger than an ordinary blade. Its true status remains one of the series' biggest mysteries.

Durandal

Durandal belongs to Cavendish and has shown impressive performance throughout the story. Although it has not received a confirmed grade, the sword's durability, sharpness, and battle record have earned it considerable attention. Many readers believe Durandal could eventually be revealed as a high-grade weapon.
