The spine and choil are polished, and the level of polish on the handle and bolster is indicative of the level of care that goes into each knife. While the steel is hard, the heat treatment method they are using works extremely well and creates an edge that sharpens easily and takes a very nice edge. They cut rather well and have amazingly good edge retention.
SABAKI BOCHO SERIES
The Blazen series has a decently tall blade height, a very thin tip, is thin behind the edge, but has some weight to it, due to the spine to edge and distal tapers. We are proud to be Ryusen's only official dealership for the Americas. Their business philosophy is such that they are open to new and better ways of doing things at every step of the way.
SABAKI BOCHO PROFESSIONAL
They have done an excellent job at both researching on their own, as well as eliciting in depth feedback from professional chefs and customers. This is extremely apparent in their most recent offerings. With this shift in philosophy, they have redoubled efforts to constantly make improvements to their various series (profiles, grinds, fit and finish, forging, heat treating, etc.). More recently, the have stopped all OEM work to focus on their own brand. Ryusen used to be one of the most popular OEM makers in Japan, as they had an excellent reputation for the knives they produced. From the forging to the heat treating to the product design and packaging, they had smart, well thought out processes in place. Likewise, it was clear they took great care and pride in each step of the knife making process, which they do entirely in-house. Their commitment to excellence in grind quality, fit and finish, and consistency in each line they made was most impressive.

When visiting Echizen on one of our Japan trips, we met with Ryusen Hamono, the maker of Blazen knives. Since that time, they have gotten better. Even back then, they were known for exceptional edge retention and a great distal taper. A long time ago, when I was still cooking professionally, Blazen was one of my first serious Japanese knives. The Blazen series features an SG2 core (a powdered stainless steel), clad in softer stainless steel.
