Kosso (Pterocarpus erinaceus), also sold as Senegal Rosewood in some markets, is a West African hardwood with gorgeous color and grain. It looks similar to Kiaat, another member of the Pterocarpus genus.The heartwood ranges through warm reddish-brown to deep red-purple tones, often with darker streaks and attractive figure, and it finishes to a rich luster. Like other Pterocarpus species, it's durable, stable and works well, turning and finishing nicely.Its beauty has made it heavily exploited for “Hongmu,” the traditional rosewood-style furniture popular in China, and it's now considered an endangered species. That demand has made legal supply very limited, and it's become one of the rarer woods we carry.Kosso suits boxes, cabinetry, inlay, knife handles, pens and specialty pieces where its color can shine. Our stock is limited, and we don't expect to be able to replace it once it's gone. For a similar look, see African Padauk and Kiaat.
