I used these for the first time on Wednesday (in my Dark Stag folding Kamisori). First impression... Decent sharpness and reasonably smooth. After three passes I had a couple of nicks and some mild irritation but also a nice smooth shave. I have reasonably tough growth and it had been about two days since I last shaved. I will definately be using these again and will be keeping them in frequent rotation. Next time I might try a quick palm strop first.
