I've tried a couple of the carbon blades and I'm not a fan.1918 Gillette Thin Cap Old Type / vintage Mohawk "SuperFine" carbon blade (1 and done) / Stirling Ozark Mountain / Pinaud Clubman AS / I got 3 shaves with the last one, and maybe it was the razor, but this one was a lot of tug, so I binned it afterward. If nothing else, the old carbon blades force me to focus more than a modern blade which can cover for a lot of technique mistakes--kind of like winter driving with all-wheel drive, anti-lock brakes and traction control...
