Wondering if anyone has any insight into what seems to be a change in focus with Yu Kurosaki and his knife production? He used to produce a greater variety of knife steels and styles (mostly Tsuchime styles I guess) and now seems to be producing mostly Senko and Gekko lines of knives. I have and very much like some of his earlier work and wonder of others perhaps know more about this seeming shift, or if I am just looking in the wrong places?
