Walnut is a tough wood with medium density, bending and crushing properties, with low stiffness and moderate shock resistance. Walnut machines well and can be worked relatively easily with either hand or machine tools. A moderate blunting effect is to be expected on cutting edges. It has good steam-bending properties, holds nails and screws well, and can be glued satisfactorily. Walnut can be stained or polished to an exceptional finish and develops a rich patina that gains luster as it ages. Medium to dark stains are most popular for finishing Walnut.
