Two hammers are traditionally thrown in the Heavy Events, at 16 lb. hammer (same as the modern Olympic hammer in weight) and a 22 lb. hammer. These events are the ancient ancestors of the modern Olympic hammer throw. Unlike the modern form of the Olympic hammer, the Scottish hammers have a rattan handle (closer to the original Blacksmith's hammer that was thrown) and are thrown from a stationary position behind a trig that cannot be stepped on or over as in the previous two events. Athletes generally attach a 3 to 6 inch spike on the sole of a pair of boots for this event so that they can dig their feet into the ground to provide greater stability and exert more force on the hammer.
