Hardness Scale

For the good folks at "Williams Pharmacy," who sent me "their" newsletter with the subject "Turn your tool into rock hard steel":

Just to say that I'm pretty certain I'd want any steel tool of mine to be considerably harder than most rock, never mind the fact that a tool is much more useful as a tool than as a chunk of metal.

Oh, yeah. Good point. It makes much more sense now.
