Presently, the world is home to over 100,000 distinct varieties of wood. The hardness of each type is identified using the Janka Wood Hardness Scale, measured in pounds-force (lbf). A higher lbf rating indicates a harder wood. In this article, we will explore the top 10+ hardest woods in the world, as determined by their Janka hardness ratings.
