From BlacksmithSONG: the Kuro Kabuto replica, its frame in solid die-cast zinc alloy — 16cm (6.3"), 87g (3.1 oz), shipped free worldwide with tracking. The Straw Hat crew’s sniper finally gets a perch on your shelf: a matte black ring, a white-wrapped grip, and five elastic cords running back to a star-shaped pouch.
Kuro Kabuto is Usopp’s slingshot after the two-year timeskip, the black successor to his earlier Kabuto. He loads it with Pop Green seeds from the Boin Archipelago, where he trained under Heracles, and the weapon carries a living plant of its own. Ours is a fan-made tribute to that One Piece weapon, unofficial and unaffiliated.
Every photo on this page is ours, shot in our own studio on the exact piece that goes in your box. That includes the stretched-cord shot: the elastic really does have give, and we wanted you to see it before you buy. No CGI, no renders, no supplier images.

It’s about as long as a big-screen smartphone, measured from the tip of the ring to the end of the handle. The cords and pouch hang loose past that. At 87g (3.1 oz) it carries about as much metal as the 24cm katanas in this vault, so it has real weight in the palm. The in-hand shots show the true scale.
The ring frame and shaft are die-cast in zinc alloy, then hand-finished in matte black. The ring is cast as an open C rather than a closed circle, and five small tabs inside it anchor the cords. The grip gets a white wrap, and every edge comes out of the mold rounded and blunt. The rest of the line is in our long-form guide to the whole lineup.
Take it bare, or add a Small Display Stand (+$2), Large Display Stand (+$3), or Vertical Stand (+$4). The vertical stand holds it upright with the ring on top, which reads best on a crowded shelf. It lives in the Grand Line Katana Vault, and it’s a welcome oddball on our exotic weapons shelf. The only other piece in the vault that skips the sword entirely is Sabo's 22cm pipe — Luffy's sniper and Luffy's brother, side by side.
Free worldwide tracked shipping — about a 10-day median, longer if customs holds it — a foam-lined gift box, and a 30-day money-back guarantee. Fan-made, unofficial, and not affiliated with anyone — the full story is on our fan art policy page. Kuro Kabuto, 16cm, cords and all, ready for the shelf.
Usopp never sails alone: his crewmate Zoro’s white katana, the Wado Ichimonji, is already in the vault.

The stuff collectors actually ask us.
About the length of a big-screen smartphone, from the tip of the ring frame to the end of the handle. The elastic cords and pouch hang free past that. It weighs 87g (3.1 oz), close to the 24cm katanas in this line, so it feels solid in the hand. The in-hand photos above show the true scale.
No — it’s a display collectible, not a functional weapon. The frame is cast blunt, and the cords stretch just enough to pose a draw for photos, but it isn’t built to launch anything, so please don’t load it. Display only, recommended for ages 14+.
No, and we’d rather tell you up front. The ring frame and shaft are die-cast zinc alloy, hand-finished in matte black, and that’s where the 87g (3.1 oz) comes from. The grip has a white wrap, and the five cords are real elastic ending in a soft star-shaped pouch, so the draw looks right instead of frozen in metal.
Kuro is Japanese for “black,” so the name reads as “Black Kabuto.” It follows the Kabuto slingshot Usopp carried before the timeskip, and it’s the one he fires Pop Green seeds from after it. This piece is an unofficial fan-art take on it at 16cm (6.3"), with a matte black frame and five black cords.
No — and we say so on our own page. This is an unofficial fan-art collectible from a two-person studio, not affiliated with, endorsed by, or licensed by any game, anime, or film company. There's no official packaging or certificate, because there isn't one to give you.
Free worldwide tracked shipping. Typical delivery is about 10 days — the median across 150+ tracked deliveries, US and international alike — though customs can stretch a small share to three or four weeks. Payment options are shown at checkout. Every order carries a 30-day money-back guarantee.
