So, I'm starting my second year of shaving with a straight razor. I shave every day with a straight. I still have one remaining spot that frustrates the heck out of me: the corners of my mouth. For me it's hard to shave, very sensitive to xtg or atg, oh, and did I mention, very prone to bleeding at even the slightest nick.

Please pardon if this has been discussed ad infinitum. You may simply direct me to the link, however my search showed no direct thread.

So, I wonder what are your tough spots, and how do you deal with them?
