So this is what I have discovered so far, (after 3 weeks)...

My #1 rule, always shave downwards, no more nicks.

My #2 rule, don't try any other crazy directions.

After my third sting, I realized that the red line was almost vertical, just like the other two. It then dawned on me as to why I had the red line on my face, (see rule #1 or #2). I can almost shave my entire face now but I still fear the chin and the upper lip. I suppose they will come in time.

Also the purchase of a new 5/8 Dovo has helped. I find the narrower blade easier to handle...
