A DE razor blade in practice has four cutting edges, place in your razor with 1&2 showing- after two shaves flip it over and rinse it, then you are ready for shaves 3&4. I use this method myself, which is why I prefer a razor with a butterfly opening, a Gillette Adjustable Fatboy 1959.Some blades have numbers on it. 1 & 2 on 1 side, 3 & 4 on the other side.
What's the use of it? First I thought to see which side you're using. But when in the razor you can't see those numbers.View attachment 41679
Because there are four grinding wheels grinding the blade as it goes through the line, in QC if they find one of the grinds are bad they can look at the number and check the correct grinding wheel. P.Why would having identical numbers on every blade have anything to do with quality control?
