I guess a progress report is in order first... about 10 shaves in. Can shave WTG confidently with both hands. Shave isn't exactly close enough that I feel confident going to work though. Can shave XTG with my right hand (on the left side of my face) fairly confidently. When it comes to using the sinister left hand, however, I'm still cutting myself. Not nicking, but actually cutting. This is very frustrating... After going XTG it's pretty close, but the cutting actually made one of my co-workers ask if I got attacked by a cat (no joke).

Is there an actual benefit to using both hands? Exactly what doorways does this open up later on?
