shear cutting

Cutting offers the best chance of taking a narrow shaving, minimizing grain pickup. "Shear scraping," which is cutting without benefit of bevel does pretty much the same thing. Flat scraping will bend fiber of necessity, and must be done with a very fine touch to minimize chances of digging in which a bevel would take care of.

You have to be steep enough on the bevel to get the nose of the gouge inside and the bevel in contact while not hitting the opposite rim with the tool as you enter. My thicker bowl gouges are ground to longer bevel angles than my thinner, because they don't have to get into narrow spots.
