Clash sells one main premium plastic, Steady, and nearly the whole range comes in it. Around it sit Sunny, a stiffer blend for heat and torque, and a pair of putter plastics, Hardy and Softy, that split the firmness question in two.
Tone is the odd one out: a dual-density overmould with a stiff rim and grippy top, on one mould. Special Blend is a limited Steady-like formula that shows up on specific releases.
