I normally do a single pass before work in the morning, but since this week is vacation, I've been taking more time in the morning. I have inadvertently become quite good at a one-pass shave.
I noticed when I went to lather up for the second pass I always had a slight burning sensation. Since a good artist doesn't blame his tools, I made sure to check the sharpness of the razor, check my stropping, check my prep, try some new skin stretches, and reduce the pressure. Today it all came together, or so I thought. feathery touch with my 4/8 quarter-hollow, nice long hot soak, great stretching. The shave felt great in every way. Re-lathered to do it again, and I felt the same burning. There was no way I had scraped myself too aggressively, so I was confused. Then I realized that the burn was consistent over the entire shaved area, which also didn't fit in with razor burn, as I tend to irritate some areas and not others.
I think I must have a slight sensitivity to the soap I'm using (Classic Shaving sandalwood). It isn't enough that I notice it the first time I lather, but putting it on freshly shaved skin does irritate.
The good news, however, is that I've become very adept at a one-pass shave. I'm excited for when this puck is gone and I can start on the other cake of MamaBear's that I have, and see what I can do when I can start doing two passes again.
