Grain Pattern
Mostly straight, fine-textured grain with subtle cathedral movement and a small knot/void; likely flat-sawn or plain-sawn.

AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.
- Wood Age Estimate
- Cannot be reliably estimated from a photo; it appears relatively clean and recently machined, without clear patina or wear evidence.
Common Uses
Furniture, cabinetry, flooring, architectural millwork, gunstocks, veneer, turning, and musical instruments.
Geographic Origin
Eastern and central North America, especially the Midwest and Appalachian regions.
Workability
Generally machines, sands, glues, and finishes well; occasional tearout occurs around knots or reversing grain. Pre-drilling is advisable for fasteners.
Finish Recommendations
Use a clear oil, wiping varnish, lacquer, or polyurethane after sanding to 180–220 grit; seal end grain and test for blotching or color shift.
Notable Features
Moderate weight, fine texture, good dimensional stability, and characteristic dark streaking; the visible void may indicate a knot or bark inclusion.
