Market Value & Sustainability
Estimated Market Value
$12.00 - $18.00 per board foot depending on grade and width.
Wood Age Estimate

Workability
Excellent workability with both hand and machine tools; glues, stains, and finishes very well. Can sometimes have tearout if the grain is irregular during planing.
Notable Features
Faint, mild odor when being worked; known for its excellent dimensional stability and shock resistance.
Finish Recommendations
High-quality oils (tung/linseed) to enhance depth or polyurethane for durability; shellac works well as a sealer.
Identification Confidence
High; the color range, grain structure, and the segment-stacked lamination style are classic hallmarks of American Black Walnut craft turnery.
