Hinokuni Gyuto Shirogami #1 180mm (7.1″)

The Hinokuni Gyuto is a versatile kitchen knife made entirely by hand by blacksmith Yukihiro-san at his smithy in Kumamoto in the south of Japan. The Hinokuni collection is hand-forged from Shirogami #1 steel laminated in soft iron, so sharpening will be nothing but pure pleasure.

Few blacksmiths make their own knives completely in every step of the process from raw material to finished product, and Yukihiro-san is one of them. Working with raw materials is challenging and difficult, but the blacksmith insists on it because he believes that this step is crucial for the quality of the final product. The result of such a long and hard process are sturdy and heavy knives that are real workhorses.

❗️Because they are forged by hand and in small quantities, they take a while to arrive, so here’s some good advice: if one of the knives from the Hinokuni series is on your wish list, get it while it’s still available.

🌋 Hinokuni means “the land of fire”, a nickname for Kumamoto Prefecture, home to the famous volcano Mt. Aso.

BLADE SHAPE:
The 180mm long gyuto is a versatile kitchen knife that excels at all types of chopping and cutting on the cutting board. The wide blade is great for chopping vegetables and allows easy transfer of ingredients from the board to the pot, and the extra weight can be used to cut through tougher ingredients (🚨 but not through bones!). Thanks to its long and thin cutting edge, this knife has no problem with longer cuts and finer techniques such as chopping garlic, dicing or julienne.

STEEL:
Yukihiro San uses only Shirogami #1 for his kitchen knives, which is very reactive and delicate, but unparalleled in its sharpness.

Shirogami #1 is one of the purest steels, and consequently one of the easiest to sharpen. Its characteristics make Shirogami popular with traditional Japanese blacksmiths and sushi masters. The advantage of Shirogami #1 is that it has a very fine, delicate sharpness, is easy to grind and stays sharp for a very long time. It will require a little more attention in maintenance. The blade will acquire a protective patina with use.

KNIFE CARE:
The steel will gradually acquire a patina, which only endows this knife with more charm. Do not wash this knife in a dishwasher, but rather wash it by hand and wipe it with a dry cloth. The advantage of having a blade made of high carbon steel is the fine sharpness, ease of sharpening, and long edge retention. We recommend the occasional coat of knife maintenance oil to protect the blade from external influences.

LAMINATION:
The blade was laminated with soft iron, which is iron with only a small amount of carbon added to it. Laminating the blade improves its structural integrity, as the knife’s core is made of hard—and therefore brittle—high-carbon Shirogami #1 steel that is prone to breakage on its own.

⚠️ Due to its purity and lack of any added elements such as chromium (Cr), soft iron doesn’t resist corrosion well. Therefore, the upper laminated part can also develop rust when not taken care of properly.

→ Yukihiro-san laminates the knives himself in his smithy because he sees this as a crucial step in the processing of the blade. The process of laminating different metals is very complex, and most smithies use pre-laminated materials.

GEOMETRY:
It has a double bevel (symmetrical) blade.

BLADE FINISH:
The blade sports a beautiful black Kuro-uchi finish.

The look of the knife reflects the blacksmith’s philosophy and has a touch of rusticity and robustness that comes with the purely handmade blade. The knife has been created with a great deal of pride and skill.

HANDLE:
The Japanese Wa handle is oval and made in cherry wood with a plastic ferrule. It fits perfectly in the left and right hand.

BLACKSMITH:
Yukihiro Sakai is a young blacksmith from Kumamoto (Kumamoto Prefecture on the island of Kyushu). He trained with Nishida-san [Nishida Hamono]. Yukihiro-San’s recent work is focused on Shirogami #1 with a kuro-uchi finish and evenly ground and flat profiles. His knives are affordable but of superior quality. We anticipate that over the years, the prices of his products will rise due to the superb craftsmanship and his growing popularity.
