I have struggled with terrible razor burn for the past 20 years - nothing I did helped. I tried straight razors, Gillette SkinGuard, safety razors, electric razors. I even went a whole year without being clean-shaven, instead just trimming to stubble with a hair trimmer (no razor burn that way, but never clean shaven). I saw Supply on advertise and thought, "what the heck, it can't make it worse," and I'm glad I took the chance!
The weight and the firmness of the blade seem to make all the difference, and what actually makes it different from the other things I tried. When I use normal razors, there is a lot of tugging/pulling on the beard, with the Supply razor, that is completely eliminated, and I can use very light pressure, as to not cut too close to the skin. When you use a light weight razor and try to apply light pressure, the razor "bounces" off the stubble, causing it to pull and tug, so you have to push to keep it on the face - that then causes the stubble to be cut too close to the skin, and I wake up with razor burn the next morning. With Supply, the heavy weight takes care of the "bouncing" problem, and I can achieve just the right "closeness", as to be clean shaven, without cutting too close.
The picture I posted is the morning 24 hours post shave, when I would normally experience the worst razor burn, covering a large portion of my neck. Here you see, it is all but gone! I've been shaving with this razor for a few weeks now, and the picture is after about 10 shaves. Supply has earned a life-long customer. I'm sure mileage will vary depending on stubble coarseness, but I am able to achieve 5 shaves per blade before experiencing pulling. I shave about 5 times a week, so that's $4 a month for Black Label blades - great price!
If you have sensitive skin issues, you have to try this razor - it could change your life.
