Katalox - swartzia Cubenis
This very hard, dense, heavy, Central/Latin American wood has a generally dark purple and brown heartwood that can show considerable color variation. Katalox can be quite attractive and it takes a high natural polish and sometimes has interlocked grain that can create an attractive curl in the figure. Finishing agents will turn darker pieces almost black, after which it can be difficult to distinguish from partridgewood due to the similar wenge-like, but very tight, grain pattern. Katalox is ideal for an Ebony substitute in stringed instruments and is nearly as dense as Ebony.
