Hammer Bowling means high-performing products to help any bowler compete at their best, but not everyone needs a performance ball. The Axe is a perfect spare ball for a Hammer fan or an excellent option for a recreational bowler looking for their first ball. The Axe is one of a kind, using a harder, more durable reactive resin called Low Friction Reactive. The durable reactive shell, along with a 3-piece core, is a unique offering and provides predictability and confidence.
