This isn't directly related to method shaving, but I need method shavers to respond, because they'r the best test group..
My philosophy has always been that I could shave clean with any razor if I was willing to pay the price. I've measured closeness by how long it takes to begin stubbling up. My shaving procedure is essentially consistent, and that's why I'm addressing method shavers: I want input from people who follow a consistent procedure. I would love input from the method shaving veterans who must have lots of experience with different people.
I'm trying to determine two things: the consistency of your time to minimum stubble (whatever your approach is- it would be interesting if you described it) with a given razor and blade; and the actual range of the time with different razors and blades. Don't look at the long term, because we know hair growth changes with season and such. But let's look at a period of a few weeks.
I'll start the ball rolling. With a particular razor and blade (as long as it feels sharp) I get very consistent results. It's easily within half an hour. I'm a perfectionist , so I now finish off every shave with an injector using a cut off Feather str8 blade. It lets me get every last whisker. When the stubble starts coming in it now seems to be a little thicker (or more uniform over an area) than before. To judge stubble-up, I feel my entire face for stubble. I usually find it first in the same spot (actually one of two spots).
My results have been as follows: Futur/Feather 10 hrs; slant/Feather 9hrs; Vision or Progress with Feather or str8 (Feather str8 seems to be somewhat better than others) 8+ hrs; DEs with Merkur, Personna and Wilkinson blades 6-7 hrs. (Vision and slant at the high end; Futur and Progress in the middle; and Gillette adjustable at the lower); Gillette M3P motorized 5+ hrs. I also tried the injector with the Feather str8 blade for a full shave but it was dificult to use, although it's great for touchup, so I don't have any results for it. Results for injectors with personna blades were the same as the lower end of the general DE category.
Please participate and let us know whatever information you have. I'm particularly interested in the variation of your results with a fixed setup. So, if you always use the same one that is extremely important information to me.
Thanks for your response.
