"Petrified", of course.

If you don't like that answer, I'd suggest a Google search.

The United States Forest Products Laboratory has lots of material on the strength of woods. and hardness.

Heheh. Amen, brother!

Ya know, though, technically speaking, "pertrified" isn't a type of wood, is it? More like a state of transformation. Before it petrified it had some species.

Prove to me it didn't grow that way....

well, there's no real line. lots of species absorb minerals as they grow and have enough in them to be hard on tooling all along. they fall, get buried, absorb more and more and eventually the organic stuff gets completely displaced.

You forgot to mention the difference between side hardness and end-grain hardness. Not to mention which side?

This all goes to show that this is a quite complicated question after extremes (i.e. after the uncommon). PvR
