The janka hardness test is a measurement of the force necessary to embed a .444-inch
steel ball to half its diameter in wood. It is the industry standard for gauging
the ability of various species to tolerate denting and normal wear, as well as being
a good indication of the effort required to ether nail or saw the particular wood.
The higher the number the harder the wood.
