( Quoted from The Wood Database site here --> https://www.wood-database.com/black-walnut/ )
"...It would be hard to overstate Black Walnut’s popularity among woodworkers in the United States. Its cooperative working characteristics, coupled with its rich brown coloration puts 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."
