This is a custom Konosuke Fujiyama series 330mm sakimaru takobiki in blue#1 steel. It has an ebony handle with a silver spacer. I got this direct from Konosuke about 4 years ago, and it is a great performer - easy to wield, not too heavy, and not too thin. It is one of my favorite sashimi knives I've used (and those who know me know I've had a lot). No chips and straight as an arrow. There is some patina on the blade from use. Comes with saya and original box. A similarly spec'd sakimaru would run over $700 today.
