D&D: The Worth of Steel
Kudar Kanth is a dwarven martial centered on combat with short-hafted impact weapons, with shields or two-handed, including the accurate throwing of the same. There are two competing "schools" of the art, with the Landsenders practicing a version that uses hammers and the Docalcan version using axes, but the techniques are similar enough that a skilled practitioner can freely switch between the two.
Kudar Kanth is so popular among dwarves that it's virtually universal. Almost every dwarf has practiced the art at some point in their long lives.
