Ping 2021 Kushin 4 Putter

Kushin 4: A steel weight in the heel and tungsten in the toe create forgiveness, while parallel and perpendicular visual cues make alignment easier for strong-arc players.

Shallow, Uniform Grooves: Shallower grooves are uniform depth across the face combine with the dual-durometer insert to provide a soft feel and consistent roll.
Dual-Durometer Insert: The front layer of Pebax is softer for precision on shorter putts, while the back layer is firmer to ensure distance control on longer ones.
Multi-Material Construction: Different materials of varying densities (17-4 SS, tungsten, aluminium) increase MOI and optimise the CG for more forgiveness.
