Black walnut is native to eastern and central North America.
Workability
Generally machines, sands, and glues well; sharp tools help maintain clean cuts, and figured grain can tear out during planing.

Sand evenly and apply oil, shellac, lacquer, or polyurethane; a clear finish typically enriches the brown tones.
Notable Features
Recognized commonly for brown heartwood and attractive dark grain; this sample’s pronounced stripes are not diagnostic by themselves.
