After ~4mnths of daily use of a str8, I feel like I've done all I can on the side of my face where my mentally-dominant eye is. Seems a perfect shave nearly every time.

It is the side of my face away from my dominant eye where I have problems. My right-eye dominance is extremely strong: if I hold a thumb at arm's length and align it with a distant telephone pole with both eyes open and then close each eye individually, the pole/thumb relationship practically doesn't move at all with the right eye and drastically moves when only the left's open.

So I don't really shave that side particularly close with any regularity because seeing things is so difficult. This morning I dared shave a stroke jawline-and-above going from earlobe to chin corner basically being blind of the razor, using the sense of touch and hearing to guide things. It was scary and worked well. I'm tempted to try the more complex geometry below the jawline, where only aside/against grain strokes will work and where no matter what I try I just can't get a good enough look at things to be safe.

Do any of ya'll experienced vets shave blind and go by feel w/ the straight?
