I started a new Wilkinson Sword Light Brigade blade on Monday. First day was a #15 Aristocrat, second day was a President and third day was a New Standard. All wonderful BBS shaves. I was feeling brave this morning for the fourth shave and loaded it into my Merkur Slant. I reckon it took four of my seven layers of skin and every skerrick of whisker I had. I think it scared the whiskers into not growing because it's now 10 hours later and I've still pretty much got BBS. Crickey those blades are sharp after three triple pass shaves.
