I am considering a slant, but there is a nagging question. I get it that the blade is held to make the edge stay at a slight angle and that drawing this angled blade across your whiskers enhances the slicing effect. How does it differ from simply holding a non-slant at such an angle? Given that very few strokes are going to be perfectly perpendicular to the line of the blade, I cannot figure out why it would be materially different, other than looking cool. Please set me straight.
