In the hammer throughing event what is the shape of the hammer?

In the hammer throwing event, the hammer consists of a heavy metal ball, typically weighing 7.26 kg for men and 4 kg for women, attached to a long wire (about 1.2 meters) with a handle. The ball itself is spherical in shape, allowing for a smooth and aerodynamic throw. The design is intended to maximize distance while providing the thrower with a stable grip during the spin and release.
