I've been doing some investigation and I find that the sharpest blade I know, the Feather, has scratch lines that are perpendicular to the edge. All commercial razor blades have such lines, and many are sharper than a hand honed str8. So, I've begun to woner if the slanted lines are really better in some way.
Maybe it is just historical because of the size of stones. Maybe it has something to do with hand sharpening.
Has anyone looked at a brand new str8 under a microscope and noticed how the scratch lines from the factory look?
