Today was the fourth shave with the Razorpit “sharpened” DE blade. The shave was excellent, as smooth as on Day 2. Much better than Day 4 of the non-treated day. As far as I’m concerned, it’s not the longevity of the blade that interests me, it’s the potential to have a sharp, smooth, nick-free blade for as many shaves as I get. Day 5 is the real test, as my baseline blade had crapped out by that time.
