Why cross-grinding is (not always) bad

Cross-grind to make the blades "flat." Put the right hollow on with the parallel stone. I put "flat" in quotes in #1 because I want to bring up a point about cross-grinding that seems to have been forgotten: When you cross-grind a skate blade, the hollow does not become flat. It takes the radius of the grinding wheel.
