For years I used a (1950s?) fat-handled Gillette Tech with a Platinum Lord blade, which I found the best combination for sensitive skin, but it usually left me with some redness on my chin. On holidays I would sometimes use a disposable razor and found it very comfortable, but back home I stayed with the Tech because of the purist streak in me. A few months ago, however, I decided to stop ignoring reality so I bought a Gillette Contour - two blades with a swivel. It's very good - no redness and a good shave. But I only shave a couple of times a week and I found that after two days I was getting skin prickle. So I tried two passes - Contour for the first and Tech for the second, and this seems to work: no chin redness and no prickle. Does anyone else combine razors in the same shave?
