I had not used a Chinese Gillette Wilkinson Sword blade for a few months and did so today with the downright "dirty" Haymarket Vetiver by Shannon's Soaps. By dirty I mean very, very "earthy" to the point of being dark.
This blade has to be the best buy extant for the quality it exudes. Yes, it can even be bought cheaper than the Astra SP. I don't know what ancient Chinese secret Gillette is using in Shanghai but their DE blades there are simply fantastic. The only problem is finding a vendor who will determine if it is made in China or India, the latter not being quite as good IMO.
