Common Uses

Furniture, cabinetry, tables, flooring, gunstocks, veneer, turning, and decorative millwork.

Geographic Origin

Eastern and central North America, especially the Midwest and Appalachians.

Workability

Generally machines, sands, glues, and finishes well; knots can cause tearout and localized blade wear. Pre-drilling is advisable near knots.

Finish Recommendations

Use a clear oil, hardwax oil, shellac, lacquer, or polyurethane after sanding to 180–220 grit; a wash coat can reduce uneven absorption.

Notable Features

Distinctive dark knots, attractive color variation, moderate luster, and good dimensional stability.
