Koa wood is a rare tropical hardwood that grows throughout the state of Hawaii, mostly on the Big Island. In the 50 years that it takes the tree to mature, it can grow to heights of 100 feet. Acacia koa is most often found growing in the acidic soils on the slopes of extinct volcanoes at altitudes of 1,500 to 6,000 feet – land that was once covered with molten lava. Acacia koa grown at lower altitudes and in drier soils does not produce the same type of wood that is found in the trees grown at higher elevations, which displays fibers that have a luminescent quality that gives a hologram effect. The color of koa wood ranges from blonde to a dark chocolate brown, with the most common color being a reddish brown. Koa wood that has a wavy grain pattern is called curly koa, and is the most rare grade of koa, but also in highest demand. The curly grain is produced in part by the genetics of the tree and also by stress on the wood as it grows. The extra waviness brings out the shiny fibers of the wood, and highlights the extra depth that koa seems to have once it has been finished. Koa wood harvesting is limited to naturally fallen trees in order to preserve existing koa forests.

The koa we receive comes to us unfinished. We then sand and finish it with a clear coat that enhances and showcases the grain patterns to accentuate the depth and luminescence that koa is famous for. After the finish has been applied, the sticks are rubbed with a special wax to seal the finish and maintain the satin shine of the wood. The entire finishing process is done by hand, one stick at a time. Each step of the process is carefully executed, and this strict quality control ensures that every koa frame is the product of master craftsmanship.
