Pretty sure I set a world record for ruining an edge. Fourth shave I can't shave hair of the back of my knuckle. Not sure what I did but evidently I did something terribly strong. I just left the house, won't be home for a month. Not much I can do but go back to my Safety Razor. Not quite sure if it was a smart thing on my part diving into Straight Shaving beiorng a trucker.
