I noticed a guy using a black permanent marker to mark the end
surface of a drill bit before sharpening it with a Drill Doctor. I
have used a marker to paint a chisel surface before sharpening the
chisel. Anything wrong with it? Anything better?

Thanks.

You can use anything that leaves a mark. I wouldn't use Prussian blue
because of the mess, though. You just need to see where you've been
and what you missed.

Could a marker act as a lubricant, too?

Just guessing.

So one can recognize the sharp end, one supposes :-)
I have used a marker when sharpening with the Drill Doctor to
determine when I have sharpened the full edge but not the full area
behind the edge. When you have established the relief angle, whats the
point of further grinding?
