Koa

Acacia koa

koa woodKoa is the largest endemic tree in Hawai‘i–the species exists naturally nowhere else in the world. It is the fastest growing of Hawaii’s valuable hardwoods. It can grow as much as an inch in diameter per year, reaching 100 feet in height, attaining a trunk diameter of 5 feet or more. It was historically the material of choice for carved ocean-going canoes. Koa wood is the most prized cabinet and furniture wood in Hawai‘i. Colors range from light brown to deep red/brown hues. Highly figured koa is sought after for use in fine furniture, musical instruments, crafts, gunstocks, and knife handles. Koa has weight and strength properties similar to black walnut. It is a moderately heavy wood (specific gravity .55). It is stable, works well, and takes an exceptionally rich, deeply reflective glow when finished with oils and modern varnish or laquer.
