Good job. Keep with it and the dexterity with your off hand will improve. I just had my 14th str8 shave today. My left hand still has a ways to go, but it seems that I have the strokes and holds I need to make down. Just need more time to build muscle memory.

Watching videos of others shaving reminds me that I will get to where I don't struggle with the difficult razor positions.

One other thing to focus on, there has been a recent thread here on pressure. I am getting almost no razor burn when I focus on decreasing pressure. As my mentor told me "shave the lather, not the hair".

Enjoy the journey
