Black Walnut Hardwood Slabs

One of the most enjoyed American hardwoods for its fine-yet-open grain, unique patterns, and bold dark color. Walnut is easy to cut, shape and sand, and the wood takes on an amazing look with a clear finish.

Superior Grade Walnut

Comments:
It would be hard to overstate Black Walnut’s popularity among woodworkers in the United States. Its good working characteristics, coupled with its rich brown coloration, put the wood in a class by itself among temperate-zone hardwoods. To cap it off, the wood also has good dimensional stability, shock resistance, and strength properties. In limited situations, Black Walnut can sometimes be considered an alternative to ebony and other dark-colored hardwoods.
