Now I'm about to go shave. I'm a lazy ambidextrous retired Cosmetologist, I'll go see how it turns out!I'm not really in favour of the concept. You are really buggered if you are a lefty. Just personally . . . I'd not waste a dime on a slant. But that is just me. Please feel free to curse me at your leisure.
