Gadd K1 (9)

The Kastaplast Gadd is a 2026 Kastaplast mold with a 1.4 cm rim, 1.3 cm rim depth and 21.5 cm diameter, certified by the PDGA on March 30, 2026. Catalogued as a putter by class but landing in midrange-leaning proportions — the rim sits between the brand's Berg/Reko putter line and a compact midrange — Kastaplast positions the Gadd as a slow approach mold with a comfortable beaded grip suitable for both backhand upshots and forehand stabs. As Kastaplast has not yet published full flight numbers for the Gadd, real-world flight character is best learned from throws on course; the physical specs suggest a stable to slightly overstable disc with modest glide and a dependable late finish, in line with the rest of Kastaplast's approach lineup. Kastaplast's premium K1 and K1 Hard plastics hold the original character longest, while baseline K3, K3 Soft and K3 Glow season faster toward a more understable, glide-heavy feel.

Plast: K1: K1 is Kastaplast's flagship premium blend, used across the brand's distance drivers and many fairways and putters. The plastic is translucent, fairly firm, and slightly grippy out of the box, designed for long-term flight retention and predictable behavior on full-power lines. It breaks in slowly and gracefully rather than going limp, which makes it well suited for shelf-stable bag staples players want to trust over many seasons. As a premium plastic, K1 holds its listed flight far longer than baseline blends; baseline plastics in the same mold season faster, picking up deeper turn and softer, earlier fade within a few weeks of regular play.
