I have a Gillette open comb razor (either Old Type or Single Ring... I really don't see the difference). This thing will be the death of me if I keep trying to use it. Twice now, I've carefully attempted it with a mild blade, and I've wound up "donating blood" every time. I've gone with so little pressure that the thing is just barely touching, have a good lather, and I think my blade angle is good.... yet, here I sit with world-class razor burn and a few weepers still stinging from styptic. I especially have trouble with my upper lip, and also with doing an against-the-grain pass. Can some people just not use open comb razors? Are they not intended for use against-the-grain? My daily shaver is a Gillette Slim Adjustable, and I usually survive the morning ritual without blood loss.
