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.
Placed within the Supreme Grade, the elite dozen at the top of the famous-blade rankings, this cutlass counted as one of the most formidable weapons anyone had ever crafted. Its equals could be numbered on one hand; only rare arms like the Murakumogiri that Whitebeard carried stood on its level. Roger, the Pirate King, kept it at his side as the tool most associated with him.
Where the grip meets the pommel, a golden dome forms the main guard, and a thinner secondary guard lies over the yellow hilt, which is decorated with a repeating diamond motif. The blade of standard length bends in a soft arc and carries a saw-toothed hamon running down each face, while a black scabbard holds it when sheathed. Toughness was its defining trait: throughout Roger's fights the steel never chipped. He could route two forms of Haki into it, both the Armament type and the Conqueror's variety.
Roughly thirty-eight years back, the blade came into Roger's hands. Twenty-six years ago he swung it across the four days of his final duel against Whitebeard's crew, and he also carried it during the God Valley Incident. The last confirmed sighting placed the weapon with him while the Roger Pirates searched for the Road Poneglyphs; where it went afterward, and what condition it is in, remains a mystery. Roger would go on to name his son Ace, though whether the sword steered that decision is never spelled out.

When I first decided to commit to watching One Piece seriously, I knew I was embarking on one of anime's longest and most beloved series. With over 100...

The transformation everyone knows, the follow-up question nobody would touch. Why we made a smooth R&B track about the golden glow Dragon Ball never talks about....
Ace is the cutlass belonging to Gol D. Roger, the Pirate King, ranked among the Supreme Grade, the elite dozen swords at the very top of the famous-blade rankings. It was the weapon most associated with Roger throughout his career.
The sword Ace features a golden dome guard where the grip meets the pommel, a yellow hilt decorated with a diamond motif, and a standard-length blade with a soft curve and a saw-toothed hamon. It is kept in a black scabbard when sheathed.
The sword Ace never chipped throughout any of Gol D. Roger's battles, reflecting its status as one of the most formidable blades ever forged. Roger could channel both Armament Haki and Conqueror's Haki through it.
Gol D. Roger used the sword Ace during the God Valley Incident and across his four-day final duel against Whitebeard's crew twenty-six years before the present story. It was last confirmed to be with him while the Roger Pirates searched for the Road Poneglyphs.
Roger went on to name his son Ace, though whether the sword itself inspired the name is never made clear in the story.
