The shape of this knife that we call the Funayuki Gyuto is flatter on the edge for better push cutting. Konosuke Fujiyama series is a group of knives that are made by a particular blacksmith that does excellent work. This group of knives uses Blue #2 steel which is made by Hitachi and is also called Aogami #2 and sometimes called Blue Paper #2 since the steel is wrapped in blue paper when it's sent to blacksmiths. This steel is sought after and made from Japanese pure sand irons at their famous Yasugi plant in Shimane Prefecture. It has 1.10 ~1.20 high carbon with 0.20 ~0.50 Chromium and 1.00 ~1.50 Tungsten at Rockwell Rc.61~62, and it outperforms Shirogami ( White Steel) with better edge retention and ability to take a more acute edge.
Well,think this makes Kono number 8? But if you are looking for a flatter profile then look no further. Same fit and finish as the usual blue 2 but flatter. Really good for chopping. It is a little heavier than the normal one but only by a very little. Only someone who has both would be able to tell. But a great knife for those who are looking for a flatter gyuto. And the usual great service from Mark.
