What is the Janka hardness test and what does it mean to me as a consumer?
The Janka hardness rating is the standard measurement for hardness. It is conducted by measuring the force needed to lodge a .444-inch steel ball in different wood species to a depth of half the ball’s diameter. The higher the rating, the harder the species. The Janka rating is also useful when assessing how easy or difficult it is to hammer or saw the wood.
