What is the hardest wood available?
For Domestic & Exotic Wood Flooring Species: The Janka (or side) hardness test measures the force required to embed a .444 inch steel ball to half its diameter in wood. This is one of the best measures of the ability of wood species to withstand denting and wear. It is also a good indicator of how hard a species is to saw or nail. The higher the number the harder the wood.
