Koa

Koa (Acacia koa) is one of Hawaii’s most beautiful native hardwoods and grows only on the Hawaiian Islands. It’s sometimes compared to mahogany in appearance, and it holds a special place in Hawaiian culture, traditionally used for canoes and surfboards.
It’s generally medium to reddish brown, though color varies a lot, from golden to deep chocolate. Figured boards with strong curl and chatoyance are highly prized and can seem to glow under finish.
It’s quite stable and fairly easy to work, except where the grain is highly figured or interlocked, where sharp tools and light passes help. It glues and finishes well, and a clear finish brings out its depth.
Koa is a very popular instrument wood with a rich, warm tone, used widely for guitar backs and sides, tops and ukuleles. It’s also used for fine furniture, gun stocks, turnings, boxes, veneer and specialty pieces. Supply is limited, and highly figured boards command a premium. For a similar look at a friendlier price, see Australian Blackwood.
This wood species is not listed in the CITES Appendices, and is reported by the IUCN as being a species of least concern
