We use exotic woods for their unique properties, such as density, strength, flexibility, and beauty. They also offer a range of grain patterns and colors that can make each Bokken a work of art. By laminating wood together you are increasing the strength of the weapon. Bowyers have been doing this for years. By laminating the limbs of bows, you increase the flexibility and strength of the bow. When thinking in terms of bokken, you are increasing the amount of impact edges. The more impact edges you have the stronger the weapon will be. You can think of plywood as an example. The layered edge is much stronger than the face edge because you have many layers on the impact edge. The other advantage of laminating is that you can create a more customized weight and balance to the bokken. By varying the types of woods you can get different overall weights. Laminating also creates a unique and beautiful look.
