Bubinga (also known as Kevazingo)
Guibourtia spp. (G. tessmannii, G. pellegriniana) • Exotic/Tropical Hardwood
Grain Pattern
Interlocked grain with a fine to medium texture. Common figures include pommele, flame, and waterfall; this sample shows a subtle wavy interlock characteristic of knife scales.
Color Description
Heartwood ranges from a pinkish red to a darker reddish brown with darker purple or black streaks. It has a medium natural luster. The sapwood is typically a pale yellow. Darkens slightly with age and UV exposure.
Hardness Rating
2,410 lbf (Very Hard)
Durability Rating
Very Durable; rated as very resistant to termite attack and marine borers. High natural rot resistance.
Common Uses
Knife handles (scales), fine furniture, cabinetry, veneers, musical instruments (guitars and drums), and specialty turned objects.
Geographic Origin
Equatorial Africa (Gabon, Cameroon, Equatorial Guinea)
Market Value & Sustainability
Estimated Market Value
$25.00 - $50.00 per board foot for standard stock; figured pieces or large slabs are significantly higher.
Wood Age Estimate
The sample appears relatively fresh or recently worked, likely processed into scales within the last 5-10 years based on the lack of deep oxidation or patina.
Sustainability Status
All species of Bubinga are listed on CITES Appendix II; listed as Endangered on the IUCN Red List due to over-harvesting.
Workability
Generally easy to work despite its high density, though interlocked grain can cause tear-out during planing. It glues well but high natural oils may require a solvent wipe. Sands to a very high natural sheen.
Notable Features
Often has a faint, unpleasant odor when wet or freshly cut which disappears when dry. Known for its exceptional strength-to-weight ratio and vivid coloration.
Finish Recommendations
Specifically benefits from tung oil or Danish oil to pop the grain, followed by wax or a buffed CA finish for knife scales. It takes a high polish naturally.
Identification Confidence
Medium-High. The pinkish-red hue with darker streaks, large pore structure visible in the grain, and its common use in custom knife making strongly indicate Bubinga or a closely related species like Rosewood.
