Thanks for showing your various shaping tools Frankie.
I use an angle grinder/flap disc for initial removal of comfort contours too. Then fine tune with various hand tools (rasps, dowels etc).

I find a drum sander attachment in a hand drill is good for getting in around the cutaways and horns. I have whole set so I can change size as needed. They're also handy in the drill press for other jobs too.
