Konosuke Fujiyama Blue #2 Gyuto 270mm. This one comes with a really nice ebony handle with blond buffalo ferrule. 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.
