This is a Chef’s knife. Not because of the shape, but because it is all that a professional could want. It is tough and hard. It will stand up to hours of work and hold an edge for months on end. That's because it has 133 layers of super-premium steel, ice hardened to 66 on the Rockwell. All that means to me is that I love cutting with every one of these knives. It is effortless. It makes my strokes elegant and I easily get into a rhythm when I am using a Miyabi Black. I love this line!
