Common Uses

Furniture, cabinetry, flooring, veneer, gunstocks, turning, and decorative woodworking.

Geographic Origin

Eastern and central North America, especially the central and eastern United States.

Workability

Generally machines and finishes well; sharp tools help produce clean cuts. Glues readily, though grain direction matters when planing to avoid tearout.

Finish Recommendations

Sand evenly and use oil, shellac, lacquer, or polyurethane; a clear finish enhances the brown color. Seal sapwood separately if color uniformity is desired.

Notable Features

Known for rich brown heartwood, attractive figure, and good stability; the image does not reveal scent or end-grain details.
