So new to straights, I finally switched over after a year with a DE. I have watched Lynn`s video many times and pick up tiny differences each time. But my chin is the bane of my Sr shaving life. If it's close it's razor burned and the alum block let's me know. If it feels good to the block it's rough on the fingers. I'm shaving WTG. If I go against it wants to hang up and I have visions of arterial blood on the ceiling... totally false I know but the mind thinks these things. So any tips on getting around this rounded nob of frustration at the bottom of my face.

Also primarily shaving with my dominant hand only... should I get comfortable with it fir s t then t t y off hand or just go all in?

Thanks for the help
Tom
