Kohetsu Shinano Blue #2 Bunka 170mm. This line is made using the ever popular Blue #2 steel. This is by far one of the most loved steels in the world of Japanese knives. It is a high carbon steel that is known for its superior edge retention and its ability to take a more acute edge than White steels. The core steel is hardened to 62 HRC. An outer layer of stainless steel is applied san-mai style to protect and strengthen the Blue #2 inner core. It also makes daily maintenance a lot easier. San-mai translates to “three flat things” and it refers to the construction technique used in the manufacture of the blade where two layers of a softer steel are used to encase the central core or “hagane.” The core steel is exposed at the blade edge and also in the spine when viewed from above. *The felt protector fits better than the bunka saya.
The blades have a great looking matte finish which contrasts beautifully with the hamon-look line, where the hagane is exposed at the edge bevel. It has a symmetrical 50/50 grind which is particularly well executed.
