In oak, ash, and American walnut – all ring-porous hardwood species characterized by long fibers – sapwood naturally occurs. Sapwood is the lighter-colored part of the wood located closer to the bark. In products such as oak cutting boards, the presence of sapwood is a natural feature and does not constitute a material defect.

At the production stage, we place great emphasis on aesthetics. During the gluing process, we carefully match sapwood sections with sapwood to ensure a cohesive and harmonious appearance.
