The Hatsukokoro Kurogane(黒鉄, Black Iron) can be considered as the Blue 2 version of the popular Kokugei line. Main difference is the core steel is Blue 2 instead of Blue 1, and the slightly blue tint is not present on the Kotetsu, it is just as the name implies, a Kurouchi finished, iron cladding knife.

For the experienced eyes, it won't be hard to tell that this knife is made in the Tosa region. The wild hammer marks can be clearly seen under the rustic black oxidation layer. Although the finish is on the rough side, its performance is still quite decent. The bevel is a slight convex grind, but left with some thickness behind the edge, it won't fly through food like many other knives but once the cut initiates, the very positive food release will help the cut to be smooth.

The additional thickness also means the edge is on the stronger side, it can be pushed a bit harder, which kind of fits it purpose as a budget, rough use knife. For the seasoned expert, the iron cladding means the bevel geometry can be modified with relative ease, and the thicker blade can be turned into a thinner one.

I shall consider the Kurogane as a interesting brother to the Kokugei line, with their very friendly price and decent maintainability due to the Kurouchi finish, they are both a strong contender for those who are picking their first carbon steel knife. It's a knife that you can really live and explore with, which can be a valuable thing before steeping up to a more demanding and expensive knife.

Budget friendly Workhorse grind	On the thicker side Fit and finish can be improved Prone to rust

Care Instruction

Don't cut hard things! Japanese knives are brittle so bone hacking is a NO NO!
Wash with neutral detergent after use, and wipe dry;
Please don't wash knife with dishwasher, it will damage the wood handle;
Be careful not to leave the knife close to a heat source for a long time;
It is a lot more dangerous to cut with a blunt knife than a sharp knife!
It is best to sharpen a Japanese knife regularly on a waterstone.

鋼材： Blue 2 / Aogami #2
Blue Steel No.2, also recognized as Aogami No.2, is a distinguished high carbon steel produced by Hitachi Metals Ltd, enhanced by the addition of chromium and tungsten to the base of White Steel No.2. This modification brings about an improvement in toughness and the creation of hard carbide molecules, which significantly boost edge retention. Although its sharpness is comparable to that of White Steel No.2, Blue Steel No.2 offers a slight advantage in maintaining its edge.

Widely favored for its versatility, Aogami No.2 is celebrated for its ease of sharpening and robust resistance to chipping, making it an ideal choice for those new to Aogami steel knives. Containing 1.0–1.2% carbon and achieving a typical hardness of 62–63 HRC on the Rockwell scale, it stands as the benchmark in evaluating Aogami steel cutlery.

建構： Sanmai - Soft Iron Clad

Sanmai iron cladding is a traditional Japanese knife construction technique where a hard steel core is sandwiched between two layers of softer iron or steel. This method combines the superior edge retention and sharpness of high-carbon steel with the durability and ease of maintenance provided by the softer outer layers. The sanmai structure offers a balanced knife that is both flexible and resistant to breaking, ideal for precision cutting tasks. The softer outer layers also facilitate easier sharpening and contribute to the aesthetic appeal of the knife through the development of a unique patina over time. While sanmai-clad knives require careful maintenance to prevent rust, their exceptional performance and distinctive appearance make them often a desirable feature of Japanese knives.

完成： Kurouchi

Kurouchi refers to the rustic, unpolished finish found on the blade of many traditional Japanese kitchen knives. This blacksmith's finish is characterized by its dark, textured appearance, which is the result of leaving the blade forge-scale on the steel during production. Kurouchi finish not only adds a unique aesthetic appeal but also provides certain practical benefits. It acts as a protective layer against rust and corrosion, and helps to reduce food sticking to the blade during cutting. Commonly seen on high-quality, hand-forged knives, the kurouchi finish emphasizes the artisanal nature of the knife and its heritage, making each piece distinctively unique.
