Ignatz, long time no see, if I could thank you twice I would. One for each book. In the first book the author recommends wedges over full hollows and in the second just the opposite. The second pamphlet describing the hones just knocks me out. Sperm oil on a coticule ! Note the author says the Swaty has a coarse and a fine side and 30 to 40 strokes on the coarse side and 20 to 30 to finish on the fine side !.Really a trip to see someone from 1893 reviewing razors and hones along with their use.
