Konosuke White #2 Fujiyama Mioroshi Deba 270mm. This Konosuke Mioroshi Deba is a big knife. Made by hand in Sakai, the Fujiyama series knife is made with White #2 steel and measures 270mm on the blade. The handle is made of ebony with buffalo horn ferrule. The spine is rounded and this knife is thick and heavy. This steel is excellent quality and one of Kosuke's favorites because it's hard (RC61+-) and takes a great edge and is relatively easy to sharpen. The fit and finish on these knives is excellent. Handles are octagonal.
