Kiaat (Pterocarpus angiolensisis) is found in south-central Africa. It is from the same family as padauk (Pterocarpus soyauxii) which is known to be a good tonewood with sound properties somewhere between Brazilian and Indian rosewood according to the LMI catalog. It does not have as intense a red coloring as padauk but varies in color from a pale uniform brown to having irregular reddish/orange streaks and occasional flame. It has a fairly large percentage of oatmeal-colored sapwood of an inferior quality. This is generally eliminated when building guitars. Grain can be quite variable, from wavy to straight. It has excellent drying properties and dry weight is about 640KG/M3. Its strength is generally about 30% lower than padauk. It cuts, sands, and bends easily. It is moderately porous and takes any finish or polish well.

Kiaat is freely available in lumberyards in South Africa but it is very seldom quartersawn and of the necessary guitar back dimensions as is required for guitar making. Luthiers spend hours searching through piles of wood stock to find suitable size, grain, and cut.

The sap of the kiaat tree has cultural and medicinal significance. The red sap is mixed with fat and used as red face paint in tribal rituals. It has been believed to have magical healing powers especially concerning blood disorders as well as other medicinal uses. â—†
