Sorting using the list in the back of "Nick Engler's Woodworking Wisdom," by
"specific gravity," I come up with:
Hickory
Oak (white harder than red)
Maple (hard)
Birch (yellow)
Ash
Walnut
Maple (soft)
Cherry
Poplar
Aspen
Hickory is the hardest by a wide margin, and aspen is only slightly harder
than white pine.
