Any members/posters familiar with KAI double edge razor blades? I got a couple as a sample when I got my iKon bulldog handle and have to say they are smooth and sharp. Ive performed a search to see if there was a review on these blades and unfortunately came up empty. Only one shave thus far, with 3 passes in a 55 Red tip SS, and they did a real nice job. Since they are made in Japan is there any connection with Feather blades? Cheers.
