One of the the key things to shaving is developing knowledge of your face. Knowing your valleys and bumps. Knowing where you growth changes direction, mine takes a swirl under my left jaw. Today I had an unforeseen change to my face that led to a little cut. A nipper (mosquito) happened have mad a large bump right on my jaw line. Not noticing before i covered it with lather, I was going against the grain across my jaw and sliced into the mosquito bit.
Funny things happen, should have noticed it. I just thought it was an odd thing to happen.
Good night.
