How do you work the burr? Do you "fold" it over the same direction each time, do you alternate which sides you build the burr and take it off, do you even worry about the burr? Thought about it today and I usually alternate, but it makes more sense (to me) to work it the same direction each time so that the work-hardened edge is on the same "side" of the edge. What's your thoughts? I'm using one of those Lansky vise contraptions with guide rods.
