Pawel Widuto is a Polish-born fitness master now living in Norway. He is the founder of the Tengu ECS (Element Cycle System). Most longer maces like the kind made by Onnit or Set for Set are 40 inches (100cm) or more, but Pawel Widuto came up with a short mace he calls a bulava in weights ranging from 3kg (7lbs) to 11kg (24lbs).

Now for the D-ball from Jeff Martone's tacticalathlete.com. The D-Ball is like an indoor shot put. They have a rubbery grip with ridges to allow for grabbing and do not bounce. The weights range from 3lbs to 14lbs, but the diameter remains the same (5 inches) over all the available weights.
