Common Uses
Furniture, cabinetry, flooring, veneer, paneling, gunstocks, turning, and decorative woodworking.
Geographic Origin
Eastern and central North America, especially the United States.
Workability
Generally machines, planes, sands, glues, and finishes well; occasional tear-out occurs around irregular grain, and predrilling is advisable.
Finish Recommendations
Clean and sand progressively, then use hardwax oil, wiping oil, lacquer, shellac, or polyurethane; apply a washcoat or sanding sealer if blotching occurs.
Notable Features
Distinctive dark color, attractive contrast, moderate dimensional stability, and a naturally satin luster; image lacks clear end-grain evidence.
