Black Walnut and Hard Maple
Juglans nigra and Acer saccharum • Hardwood

Grain Pattern
End-grain construction featuring straight and slightly wavy grain. The walnut shows open-pored cathedral and linear patterns on the end grain, while the maple exhibits a very tight, fine, and diffuse-porous structure.
Color Description
The Walnut blocks are a deep chocolate brown with dark coffee-colored streaks; the Maple blocks range from creamy white to light golden tan. Both woods will deepen in color and develop a warm patina with age and oiling.
Hardness Rating
Walnut: 1,010 lbf (Medium); Maple: 1,450 lbf (Hard)
Durability Rating
Walnut is rated Durable (highly decay resistant); Maple is rated Non-durable (perishable to rot). However, in the context of a cutting board, both are highly durable for mechanical wear.
Common Uses
High-end furniture, cabinetry, butcher blocks, cutting boards, flooring, and musical instruments.
Geographic Origin
Eastern North America and Central United States.
Market Value & Sustainability
Estimated Market Value
Black Walnut: $12.00 - $18.00 per board foot; Hard Maple: $6.00 - $9.00 per board foot.
Wood Age Estimate
The wood appears freshly milled and newly finished, likely less than 1 year old in its current form, showing no signs of knife marks or wear.
Sustainability Status
Neither species is listed in the CITES Appendices or on the IUCN Red List; both are widely available and considered highly sustainable with FSC certification common.
Workability
Maple is difficult to plane due to density but glues well; Walnut works very easily with both hand and machine tools. Careful sanding is required to prevent dark walnut dust from contaminating the light maple pores.
Notable Features
Walnut has a faint, characteristic earthy scent; Maple is odorless and non-toxic. Walnut contains juglone, though not in significant quantities in dried wood. End-grain orientation is chosen for its 'self-healing' properties during knife use.
Finish Recommendations
Food-grade mineral oil, beeswax, or a butcher block conditioner. Avoid film-forming finishes like lacquer or polyurethane on a functional cutting surface.
Identification Confidence
High. The high-contrast 'checkerboard' mix of Black Walnut and Hard Maple is the most iconic combination for end-grain butcher blocks and is visually distinct.
