If forced to choose, Derby Extra. Sharp enough in my razors and as smooth as it gets even if they only last 4 shaves
Nice to see Derby getting the respect it deserves. Long before the pre/post 2016 theories and the introduction of the Premium line, Derbys were considered an excellent blade with positive reviews on various forums. Then a couple of guys posted about the poor shave they had and all of a sudden they were no good, rough, very poor and completely ineffective against very manly, extremely coarse stubble. Under magnification Derbys have one of the most well prepared edges available. The multiple coatings "break-in" or wear slightly after the first few shaves and the edge gets better and better. One time I shaved without looking to see what blade was in my razor. I rotate DE's and had forgotten what was in it. The shave was so smooth and comfortable. I had never felt one that good. It was as though the razor was gliding on a sheet of ice with a layer of lubricant on top. Perfect BBS results. After the shave I looked inside the razor..........Derby Extra pre-2016. They're a better blade than most think they are. And I have over 1200 of the pre-2016 thicker versions so the "rigidity" zealots will be paying big dollars to acquire even the smallest quantities of this highly sought after, much revered vintage stock.Derby
