Sky-Breaking Z15 — Solid Stainless Precision The Sky-Breaking Z15 is carved from solid stainless steel for a tough, long-lasting frame that resists rust and wear while handling high-tension bands without losing shape. Its reassuring weight (332 g) steadies your aim and adds stability for repeatable shots. Designed for comfort and control, the Z15 measures 80 mm outer fork / 50 mm inner fork / 115 mm height and features a smooth, curved ergonomic handle that reduces hand fatigue for longer sessions while providing a premium, grippy feel. For consistent accuracy the forks use a single, mirrored notch on each side, keeping band force even and balanced so the band returns on a straighter line—improving aim and shot-to-shot repeatability. Built to withstand frequent use, the Z15 delivers clean, reliable performance every shot.
