Product detail
Kurouchi is a term used by the Japanese to describe black unpolished blades. Many contemporary fans have found interesting this version for its appearance reminiscent of historical tools. Polishing of forging products was not once common. It was overtime that did not have much functional benefit, on the contrary, it made the product unnecessarily expensive. It was different with swords, where their appearance corresponded to the status of their owner.
Today we also meet with knives, where the making of kurouchi is not the result of manual work. Rather, it is an attempt to make such an impression. However, this is not the case with Yoshida Hamono, where we are talking about truly 100% hand production.
The core of the blade is hard forged from extremely hard steel ZDP-189 from the production of Hitachi Metals. The steel is forged until it reaches the optimum stage. Only an experienced blacksmith will know this. It is then quenched using the sub-zero treatment method. The result is a hardness of incredible 67 HRC. One layer of softer steel is nailed to the sides to create a traditional San Mai blade. The blade is symmetrical in the shape of the letter "V". On the blade is embossed or alternatively laser-printed inscription in kanji characters, which represents the name KYUSAKICHI and steel grade ZDP-189.
The octagonal handle is made of & nbsp; rosewood or & nbsp; maple, which is impregnated with a bio solution. This patented technology of a Norwegian company Kebony creates hard materials at the exotic teak level from commonly available woods. Its texture and color resembles rosewood. The ferrule is made of stabilized wood pakkawood.

Because it is handmade, every knife is original. The knives can differ from each other in shape, dimensions, color and the final surface treatment of the blade. The images are illustrative and the product may differ slightly from them. .

About producer
This time we will visit the southernmost of Japan's main islands - the island of Kyushu. Similar to neighboring Shikoku, mountains alternate here with a huge number of small fields. A large part of the island has an agrarian character and therefore blacksmiths have always played an important role here. The so-called "field blacksmiths" have been making tools for local farmers, fishermen and foresters for many generations.
It was no different with Seiji Yoshida, the founder of the company Yoshida Hamono. Before laying the foundation stone of his company in Saga Prefecture in 1946, he apprenticed as a blacksmith with local masters. They initiated him into the secrets of making real Japanese swords. Since then, this art has been carefully preserved in the company for several generations.
The Japanese have many qualities that could be an inspiration for us. Moderation is one of them. A Japanese does not get rid of a product as long as it serves him well. That's why he takes care of him with the proverbial thoroughness. In return, he will get a good feeling from its trouble-free and pleasant use. This is also the credo of the Yoshida Hamono company. He makes his knives from the best materials in such a way that they bring pleasure to the user every day and for an unlimited period of time.
Even though it is a family business, not a large one, Yoshida Hamono ensures complete production. He buys unique steel from Yasugi Specialty Steels /YSS/, which he then processes by hand using traditional hizukuri procedures. The handles, which are used to finalize the knives directly in the company, are also handmade
You may ask why we chose a manufacturer from Saga Prefecture, which is not one of the renowned centers of Japanese blacksmithing. The answer is simple. There are only a few manufacturers who can make genuine uchihamono from ZDP-189 steel. And Yoshida Hamono is one of them.
