I agree..........its wasteful to throw a blade out that has 3 or 4 more shaves on it. I use feathers, and get at least 5 shaves before I feel any sharpness loss.........I was wondering tho.......does it do any good to flip a blade over to get more shaves????
I've tried a blade flips, after each shave , on the third shave and even palm or dungaree strop never noticed any difference except when I stropped and that gave me 1 extra shave, not as good as a new blade. I didn't find that it was worth it.
