AK DOT basically grinds blades against asphalt in a vain attempt to rid the
roads of ice and snow. There always seems to be more where it came from. (Oh
okay, not this winter) We don't buy the same edges as dirt movers and
shapers.

I agree, they aren't so much hard as abrasion resistant and tough though
they do not bend. If you can hit one hard enough it will break. Still the
equipment and impacted object will take the worst of it and the edge will
usually lose a couple inches of a corner, maybe.

We do have some old style high carbon blades stacked in the yard and they're
workable with care and persistance. Some of it has also accidently found
it's way to my little salvage pile.
