"The Polanik Steel Competition Hammer is the go-to choice for many throwers because it offers an outstanding combination of performance, durability, and value. Polanik hammers have been trusted by Olympic and World Championship medalists for decades, earning a reputation as one of the premier brands in hammer throwing. Its small diameter provides a longer effective radius, giving athletes a big advantage when compared to a lathe-turned hammer."

Hammer FAQs
Q: Why does diameter matter in hammer throw?
A: A smaller ball diameter increases the radius from ball to hands, which multiplies rotational velocity and reduces aerodynamic drag. Both add distance.
Q: How fast does it ship?
A: In-stock orders ship within 1–2 business days from our U.S. warehouse.
