Gen 130mm Kurouchi Wa-Nakiri

The Blazen wa-series features an SG2 (powdered stainless steel) core, clad in softer stainless steel with a nashiji finish. A long time ago, when I was still cooking professionally, Blazen was one of my first serious Japanese knives. Even back then, they were known for exceptional edge retention and a great distal taper. Since that time, they have gotten better. When visiting Echizen on one of our Japan trips, we met with Ryusen Hamono, the maker of Blazen knives. Their commitment to excellence in grind quality, fit and finish, and consistency in each line they made was most impressive. Likewise, it was clear they took great care and pride in each step of the knife making process, which they do entirely in-house. From the forging to the heat treating to the product design and packaging, they had smart, well thought out processes in place. Ryusen used to be one of the most popular OEM makers in Japan, as they had an excellent reputation for the knives they produced. More recently, they have stopped all OEM work to focus on their own brand. 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.). This is extremely apparent in their most recent offerings. They have done an excellent job at both researching on their own, as well as eliciting in-depth feedback from professional chefs and customers. Their business philosophy is such that they are open to new and better ways of doing things at every step of the way. We are proud to be Ryusen's sole official dealership for the Americas.

The Blazen wa-nakiri has a very thin tip. The blade is very thin behind the edge and overall lighter-weight compared to the Western handle version due to the walnut handle. They cut rather well and have amazingly good edge retention. 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. The spine and choil are rounded, and the level of comfort on the handle and blade is indicative of the level of care that goes into each knife. 

The Bontenunryu series features a VG-10 core, clad in stainless Damascus steel. A long time ago, when I was still cooking professionally, I used knives from Ryusen. Ryusen used to be one of the most popular OEM makers in Japan, as they had an excellent reputation for the knives they produced.

The Bontenunryu series is a medium weight series.  While they aren’t super lightweight in hand, they aren’t heavy… they have a great in-hand feel. The Damascus cladding very elegant, and the fit and finish on the blade is very nice. The western style handles are also extremely well finished. The knives have nice distal taper and are ground quite thin at and behind the edge, with a medium thickness along the spine (by no means thick). The VG-10 core is exceptionally well heat treated, as they use molten salt baths in the process, which we agree is an excellent way to go about heat treating this steel. This knife comes with a ho wood saya.

The En Ginsanko series is a thin Ginsanko (stainless) knife with stainless cladding. While not quite as thin as our Gesshin Ginga or Ikazuchi series, they are almost as thin. Ginsanko is a great stainless steel that is generally easy to sharpen and takes a great edge. These knives feature a subtle convex grind on the sides and a very nice distal taper (taper from the heel to the tip along the spine). The tips are very thin. The En Ginsanko series come with ho wood octagon handles and ho wood saya.

The Fukakuryu series features an ATS-314 core, clad in stainless Damascus steel. A long time ago, when I was still cooking professionally, I used knives from Ryusen.

The Fukakuryu wa-nakiri is very thin (not quite a laser, but close) and lightweight with a dramatic angle jutting up towards the tip. The Damascus cladding is well done and not too loud, slightly muted by the acid etching on the blade. The fit and finish on the blade is very nice, including a chamfered choil. The handle is a modified octagonal maple with a coffin shape from the top down view. The ATS-314 core is exceptionally well heat treated, as they use molten salt baths in the process, which we agree is an excellent way to go about heat treating this steel.  I have found it to be easier to sharpen and less brittle than VG-10.
