Hammer created the Raw series of bowling balls to enhance an experienced bowler's arsenal and to offer beginners a performance option for their first bowling ball. The Hammer Raw Hybrid Orange/Black features the Raw Hammer core which is covered with the Juiced Hybrid coverstock then finished with a 500 then 1000 then 2000 grit Siaair sanding pad and finally polished with Crown Factory Compound. This combination of core, cover and finish gives this ball length with a strong backend and is ideal for light to medium oil.
