I don't know where this idea that doing straight strokes is a superior method to realigning an edge than the typical X stroke came from. I seriously doubt that the X stroke was developed purely out of necessity, simply because I don't think that it's ever really been that difficult throughout the course of history to get your hands on a 3 inch strip of leather. Granted, this is just my speculation: but just as the scything motion is a more effective way of cutting whiskers, it seems that the similar motion of the X stroke should be a more effective way of realigning that selfsame edge. Just the two cents of a salty 5 month veteran
