How long did it take you to find your preferred DE blade, and what were your criteria? I have found, over the decades, that my blade preferences have shaped my razor preferences and that my razor preferences have also shaped my blade preferences. Something that doesn't get mentioned nearly often enough is that time has also had a huge impact. My skin and beard are nothing like they were when I was 25. (I'm 41 at the time of this post) my beard has gone to salt and pepper and my skin is less sensitive. Starting out, my preference was for mild razors and keen blades. Since then, I have gradually started using razors that are more efficient but still on the milder side. I don't know why I still find it astonishing that people use the R41 with Feather blades. It's an insanely aggressive setup, but no more so than the person who uses a straight razor or shavette. Which brings us to the use of 'angle' and 'pressure.' Angle is fairly easy to figure out, and muscle memory will eventually replace focused concentration on that part of the shave. Pressure, on the other hand, changes with each new razor you handle. The weight and balance of the razor is different from other razors, as is blade angle, exposure, etc. I was about to do a pass with the Essence razor the other day, and I had to freeze in place. I could feel that I had placed the Feather Super AC blade at the wrong angle on my skin, and a hair more pressure would result in blood-letting. In my younger years, I'm fairly certain I would have cut myself. I had to clear away the lather in order to prove that I hadn't cut myself, because it felt like I sure had. But how does a person develop that sensitivity as quickly as possible? I used to think it was by trying a number of different razors with different blades, but now I realize that it is developed best by using a wide variety of razor types, and that blade choice is largely immaterial. The vast majority of blades will work for most people. If they didn't, the blade manufacturer would go out of business. So go out and try injectors, shavettes, SE razors and DE, and all manner of razors and blades. Be like the 90 year old violinist who still practices daily, despite 80 years of experience. To grow in the craft, you need to challenge yourself and look for new experiences.
