The Pirate King relied on a single cutlass throughout his career, and its name was Ace. Elite craftsmanship earned it a slot among the twelve Supreme Grade Blades, the rarest tier of famous swords, and across every battle Roger waged it was never once seen to crack.
Ame no Habakiri is one of the twenty-one Great Grade swords, a white katana forged by the Wano smith Kouzuki Sukiyaki. Wielded by Kouzuki Oden and later passed to his son Momonosuke, it was one of only two blades ever to wound Kaidou.
The Ancient Weapons are three world-ending relics from the Void Century, named Pluton, Poseidon, and Uranus after gods of earth, sea, and sky. Some are objects and some are living beings, and the World Government bans research on them out of fear.
An axe is a handle of wood or metal fitted with a bladed head, used throughout One Piece as both a tool and a weapon. Those who fight with one are known as axemen, and the weapon turns up often among giants and rougher fighters across the seas.
Bamboo is a longsword once carried by the Marine rear admiral T Bone. A perfectly straight and finely decorated blade, it served the officer known as the Ship Cutter until Roronoa Zoro shattered it in battle aboard the Sea Train.
The Battle Frankies are a numbered series of compact warships that Cutty Flam, later known as Franky, designed and built. Each craft is barely larger than a lifeboat yet bristles with cannons and armor, making the little vessels a match for full-size fighting ships.
The Battle Smasher is the huge prosthetic right arm strapped onto the ex-admiral Z. Cored with Seastone and armed with heavy weaponry, the oversized limb was his defining weapon across One Piece Film: Z.
Beethoven is a steel-cored whip carried by the Marine rear admiral Kujaku. Strong enough to shatter stone, it pairs with her Devil Fruit ability to bend whatever it strikes to her command.
The Brachio Tank V is a Wapometal combat vehicle housed in the Thousand Sunny's fifth Soldier Dock. Its dinosaur-shaped cannon, treads, and hidden transforming legs let the Straw Hats deploy it in pitched battles, and it can dock with another machine to form General Franky.
The Bruiser Axe was the giant battleaxe carried by Brogy of the Giant Warrior Pirates. Worn dull and brittle after countless battles, the weapon finally broke apart when he hurled himself at the Island Eater.
Buggy Balls are the explosive cannonballs favored by the pirate Buggy. A single shot can level an entire street, and over time Buggy developed shrunken versions, the marble-sized Muggy Balls, that pack the same destructive punch.
The Burn Bazooka is a Dial-powered launcher used by the Shandia warrior Wyper. It fires ordinary cannonballs by default, but a swapped-in Breath Dial lets it spew a torrent of white-blue flame.
The Burn Blade is a Dial-powered sword used by the Shandia. Little more than a wooden stick capped with a Breath Dial, it ignites stored gas to form a searing blade of flame strong enough to fell a thick tree.
Candy Jacket are armor-piercing bullets manufactured by the Big Mom Pirates. They were created specifically to punch through the reinforced bodies of the Vinsmoke siblings during the plot to wipe out the family at Sanji's wedding.
Carbonation Equipment is the line of fizzy-water-powered weaponry fielded by the Cidre Guild, an anime-original group of bounty hunters. The gear ranges from torpedoes and blasters to jetpacks, all driven by carbonated water drawn from the guild's island base.
The Cat Claws are the signature weapon of the pirate Kuro, a pair of furred gloves tipped with full-length katana blades on every finger. Paired with his blinding speed, they let him cut down enemies before they realize he has moved, though the blades break easily.
The Cutie Baton is the weapon carried by Porche of the Foxy Pirates. A bright yellow rod capped with white balls, it can be spun fast enough to fling out volleys of rose-shaped shuriken.
Daisenso, the Battle Spear, is Don Krieg's heaviest close-range weapon. He forms it by clamping his two shoulder-plates together, which then extend a wooden shaft and a metal point. Its head detonates on contact, making it the deadliest piece of his hidden arsenal.
Devil's Tower is a non-canon structure raised by the pirate Ganzack in Medaka's coastal village. Built to look like an armless dragon spitting golden fire, it secretly housed a giant cannon meant to level the surrounding island once Ganzack no longer needed it.
Durandal is a rapier ranked among the Famous Blades and borne by the pirate Cavendish. Made of remarkably supple iron, it soaks up crushing hits that would snap lesser swords, and it drives his elegantly titled fencing moves.
Dyna Stones are non-canon explosive minerals held as the Marines' final weapon. Contact with oxygen sets one off, and a single blast can wipe out a whole island, rivaling the Ancient Weapons. They recur across a film, a TV special, and a video game.
The Eagle Launcher is a non-canon bazooka billed as Marine Headquarters' newest and most powerful portable artillery. Despite firepower rivaling a small warship, it proves useless in the clumsy hands of its owner, Shepherd, who repeatedly turns it against his own side.
Eclipse is the saber once carried by the infamous captain Rocks D. Xebec. A single-edged blade of devastating cutting power, it could pierce battleships and harm legendary foes even without Haki. After Rocks fell at God Valley, the sword's whereabouts became unknown.
Eisen Whip is the Dial-powered sword belonging to the Skypiean priest Ohm. An Eisen Dial set in its base feeds a steady supply of Iron Cloud that forms the blade, letting Ohm reshape his weapon at will into whips, walls, fans, and spears.
Enma ranks among the Great Grade tier of famous blades, hammered out by the smith Shimotsuki Kouzaburou and later borne by Kouzuki Oden. Feared as almost unmasterable, the katana now rests with Roronoa Zoro, who accepted it after surrendering the stolen Shusui.
Queen the Plague built a line of rounds for the Beasts Pirates that carry engineered sickness instead of relying on brute impact. A single hit seeds an artificial, highly contagious virus in the target, and infected bodies then spread it onward, letting one shot ravage a whole crowd.
An explosive is any weapon that detonates after a timer, an impact, a trigger, or a remote signal, releasing a substance to harm a target or create a distraction. The One Piece world fields countless varieties, from simple bombs and cannonballs to Devil Fruit powers that turn the body itself into a weapon.
A firearm is a tube-shaped weapon that hurls projectiles at high speed by igniting explosive powder. Easier to carry, hide, and use than most melee arms, firearms rank as the second most popular weapon in the world after swords, and skilled users are known as Gunmen.
Flash Guns are a matched pair of ornate dual-barreled derringers wielded by the Shandia warrior Braham. Each one houses a Flash Dial, so that firing them releases a blinding burst of light alongside the shot, otherwise functioning like ordinary derringers.
A South Blue flintlock that pairs old-fashioned styling with a swing-out, six-chamber cylinder and a trigger built for rapid fire. Mr. 5 favors it for difficult fights, loading the chambers with his own explosive breath rather than ordinary rounds.
A specialized round built on Vegapunk's GP Flower technology. Rather than wounding, these bullets blossom enemy gunfire into harmless flowers, shutting down opposing marksmen. So far only the SWORD agent Hibari has fired them.
A compact wooden glider stowed aboard the Sexy Foxy. Shaped like a flying fox and able to clamp onto a cannonball, it lets Foxy ride a slowed projectile straight into an enemy for a devastating strike.
An oversized blade scaled to the giant battle robot General Franky. Franky rarely draws on swordplay, yet the weapon has held firm against heavy hits and anchors a pair of robot combat techniques.
A frog-styled flintlock customized for Miss Father's Day. Round-bodied with a frog's-head muzzle, it fires amphibian-shaped rounds that burst on contact, and it powers a paired attack she shares with Mr. 7.
A hulking pedal-powered fighting machine Foxy drives during the Davy Back Fight's combat round. Lurking in the Sexy Foxy's basement, it bristles with flaming boxing gloves and traps opponents alongside reflected Noro Noro Beams.
A non-canon follow-up to Foxy's earlier punching mecha, appearing in One Piece Party. Built to attack from overhead, it drops foes into a pit and pummels them with slowed-down, fire-wreathed gloves.
The saber Shanks carries as his main weapon. Of unknown rank yet undeniably formidable, it has traded blows with Supreme Grade blades and, charged with Haki, shrugged off an admiral's magma punch.
A toxic hydrogen sulfide gas unleashed on Punk Hazard. Deadly in vapor, liquid, or gel form, its compressed liquid serves as a core ingredient in Caesar Clown's mass-destruction weapon Shinokuni.
The colossal spiked kanabo that serves as Kaidou's signature weapon. Swung with monstrous strength and laced with Supreme King Haki, a single blow can flatten foes as mighty as Oden or a Gear 4 Luffy.
A lance fitted with a Heat Dial, belonging to the Skypiea priest Shura. The dial superheats the shaft until it glows red, letting a single thrust both burn and pierce its target.
A mechanical katana built by the scientist Wolf that runs electricity through its blade. Wielded by Trafalgar Law in the One Piece novel Law, it could harm even an intangible foe before being dissolved in battle.
Queen of the Beasts Pirates engineered Ice Oni, a synthetic plague he ranks above everything else he ever made. Fused with freezing gas and loaded into ammunition, it encases hosts in demon-shaped ice, strips away their reason, and kills them inside roughly an hour.
Igarappa is the disguised firearm carried by Igaram, captain of Arabasta's royal guard, during his stint as the Baroque Works agent Mr. 8. Built into a saxophone, the weapon spits a spray of bullets whenever its owner appears to play a tune.
Ironfist is the knuckle duster worn by the Marine Fullbody, the gear that lends his boxing-style strikes extra bite. It also supplies his epithet, first as plain Ironfist and later, once he armed both hands, as Double Ironfist.
Karakuri Rasento is the mechanized blade carried by the Beasts Pirates headliner Sasaki. Sheathed it passes for an ordinary broad sword, but a hidden mechanism makes its flaps fan out and spin, transforming the weapon into a whirling drill.
The Karakuri Sword is a katana belonging to the Beasts Pirates headliner Holed'em. Its owner regards it as something special, and outside the manga it proves to hide a mechanism that lets the blade behave like a flexible whip.
Kashu is a katana that sits within the fifty Skillful Grade blades. Mr. 11, an operative of Baroque Works, carried it first, then it passed to the Marine officer Tashigi after she bested him in a duel and took the sword as her own.
Kessui is the trademark polearm of the Impel Down warden Hannyabal. This unusual naginata mounts a full katana blade at each end, effectively binding two swords into a single long-reaching weapon he saves for serious fights.
Kikoku is the long odachi carried by Trafalgar Law, classed as both a cursed blade and a famous one that holds no formal grade. Law rarely cuts with the steel itself, instead channeling his Ope Ope no Mi through it to slice targets from a distance.
Standing as the Trump Siblings' crowning armament, the King Cannon appears only in the non-canon film Clockwork Island Adventure. It is a rolling gun-platform crowned by a screw-like barrel that fires drilling shells strong enough to send tremors across the sea.
