Grain Pattern

The exposed face shows mostly straight, longitudinal grain with coarse texture and dark streaks; no distinctive figure is visible. End grain is not shown, so cut orientation cannot be confirmed.

Color & Appearance

Freshly exposed wood appears yellow to golden, with darker brown streaks and marks. Black locust heartwood commonly darkens toward brown with exposure; sapwood is paler.

Hardness (Janka)

Black locust: about 1,700 lbf, Hard.

Durability & Decay Resistance

Durable to very durable heartwood; notably decay-resistant, while sapwood is less resistant.

Value & Age

Estimated Market ValueNot an official valuation

Rough black locust commonly sells for roughly $5–12 per board foot in the U.S.; price varies by region, grade, and drying.

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 estimated reliably from this view; surface weathering and dark marks do not establish the wood's age.

Common Uses

Fence posts, outdoor structures, flooring, furniture, turning, and tool handles.

Geographic Origin

Black locust is native to the Appalachian and Ozark regions of eastern North America and is widely planted elsewhere.

Workability

Hard and wear-resistant; machine and hand tools need sharp edges. Grain may tear out, but it generally glues and finishes well when properly prepared.

Finish Recommendations

For outdoor use, apply a penetrating exterior oil or suitable exterior finish; indoors, oil, varnish, or polyurethane work well. Test first because color and absorption can vary.

Notable Features

Dense, strong wood with excellent natural rot resistance; fresh wood may show a yellow-gold tone that deepens with age.
