The upper canines can grow up to 9". They are of a squashed circle shape in cross-section, almost rectangular, being about 1¾"deep and 1" wide. The tusk will curve 90 degrees or more from the root. The tusk will not lie flat on a table, as it curves somewhat backwards as it grows.
The tusks are used for digging, for combat with other hogs and in defence against predators - the lower set can inflict severe wounds.
The tusks, more often the upper set, are worked much in the way of elephant tusks with all designs obviously scaled down. They are carved predominantly for the tourist trade in East and Southern Africa.
