This is some seriously good stuff. A very well forged white steel 1 cutting layer hardened to about 66HRC. The finish of say Kunikei or Kiyohisa is finer but I've never really cared about that. It's good enough for me. The most important bits are in order, a flat back, a well formed ura and it's aligned the right way. When I lay it down the entire back makes contact with the wood, as it should.
