Bought these to try in my Dark Stag folding Kamisori. First shave was with about three days growth (coarse and tough). I have to say I was quite exited to try these and I was not disappointed. Sharp, smooth enough to feel. Great three pass shave with a bbs finish. Little irritation if any at all and only one nick (totally my fault for not paying attention!). I ended up using them every shave all week as I liked them that much. Instantly ended up in my top five rotation for a while. Similar to a good Voskhod or Rapira Sweedish Super Steel maybe. Worth a try.
