i wonder how sawmills do it? i think they have a machine that gnaws at
the
bark ...kind of
grinds it like a coffee grinder.

Debarkers are pretty much burr mills. Log is rotated into rotating burrs to
clear off the bulk of the bark.

My answer? It's one sharpening at most, so what's firm can stay there until
I cut it away. I stay safely out of the line of fire.

Then there's birch, where the flapping mess can whip your knuckles raw
before you can reach the switch to turn off the lathe.
