One80 Black J21 #04 90% Tungsten Steel Tip Darts

The One80 Black J21 #04 carries the same signature Black J21 barrel treatment as the #01 — convex curves, precision lineal cuts and radial grooving with smooth transitions between sections — built onto a torpedo-shaped, front-weighted barrel instead of a straight one.

That shape swap matters more than it looks. A torpedo barrel tapers toward the point, shifting more weight up front, which suits players who like to grip closer to the tip and want the barrel's mass working with that grip rather than sitting behind it. It's not a "better" shape than the straight #01 — the range exists so you can match the barrel to how you actually hold a dart, rather than adjusting your grip to fit the barrel.

At the tail, a wide ring-cut band gives your fingers a clear stopping point if you tend to lose track of where your back hand sits mid-throw.

Finished in the same two-colour electro titanium coating as the rest of the Black J21 range, and machined from 90% tungsten so the barrel stays slim without giving up weight.

Each set is ready to throw: three tungsten barrels, three Black J21 flights, six Proplast Vice shafts, and a point protector for the case.
