Koa is a tropical hardwood tree native to Hawaii. The wood is very strong and durable, making it ideal for furniture and musical instruments. Koa is also used for carving, veneers and inlay work. The wood has a distinctive grain pattern that makes it unique among other woods.
When working with koa wood, it is important to keep it dry to prevent warping and cracking. If the wood does get wet, it should be dried as soon as possible to avoid damage. Koa can be protected from moisture by sealing it with a clear finish or by storing it in a cool, dry place.
