Burnishing with the bevel 'riding hard' on the wood is why I don't like
to rough out with a skew.

You are right on robo. Once I get a 'bevel burnish' mark, it wants to
last thru the whole turning process and even tries to show up on my
display shelf.

Reverse sanding seems to heal the bruises somewhat, but it can leave a
scab and later a faint scar.

Arch,
taking this a step further in understanding the 'bevel burnish mark'.
As you say they don't want to go away.

My thoughts are the mark is caused by the localised drying of the wood,
caused by the friction created by the tool. This drying penetrating some
distance into the wood as the moisture in the fibres decreases.
Basically the wood shrinks back.

I wonder if the addition of moisture to the marks would 'revitalise'
the wood?

Maybe this is an experiment in the making
