This Ginsan line forged by Satoshi Nakagawa is another commissioned line by Hatsukokoro, having the Hira(平, the flate zone above the bevel) finished in a fine Migaki finish. It is slightly cheaper than its twin sister line with a mirror polish, but they are equally easy to look after with the stainless core and cladding.

The entire blade is finished reasonably well, weather it's the Hira, the bevel or the backside of the blade, the polishing remains cosistent and refined. Rounded choil and spine are there as expected and the only thing I can really say about the finish is the Kissaki of Sakimaru is not sharply defined. Oveall, quite a well done knife at this price.

The use of Ginsan steel makes the Knife even more versatile. While having a slightly better performance than VG10, the less alloy content in it will makes sharpening a whole lot easier, which is a huge plus for single bevel knife in professional setting. Meanwhile, being resistant to rust will save a lot of effort as there is no need to constantly wipe the blade while cutting, that's why I would also recommend this line to sushi students and homecook who have a bit more budget.

Satoshi Nakagawa, the maker who forged this line was the student under the legend bladesmith Kenichi Shiraki for over 20 years, he is very familiar with the behavior of steels especially the Hitachi Metal Paper Steels. This experience have garantees the great heat treatment on his knives so if you are looking for a stainless single bevel knife, this line will the more premium offering in terms of the quality.

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.

Profile: Deba

A deba knife is a traditional Japanese kitchen knife specifically designed for butchering fish, though it can also be used for poultry and other meats with smaller bones. Here are some key characteristics and features of a deba knife:

Blade Material: Deba knives are available in various materials, including traditional carbon steels such as shirogami (white steel) and blue steel, as well as stainless steel variants like molybdenum stainless steel. Carbon steel is preferred for its excellent sharpness and edge retention, while stainless steel variants are less prone to rust.

Blade Design: Deba knives typically have a single bevel blade, meaning they are sharpened completely on one side. This design is intended for right-handed use, though left-handed versions are available by special order.

Blade Geometry: The blade of a deba knife is heavy and thick-spined, with a blade length ranging from 5 to 7 inches. This design, along with the weight of the knife, allows it to easily cut through fish bones and joints.

Primary Purpose: The primary purpose of a deba knife is to break apart full fish, removing heads, fins, and bones, and filleting them. It is also suitable for butchering poultry and other meats with smaller bones.

Technique Tips: When using a deba knife, it's recommended to allow the weight of the blade to do the work. A sturdy grip is essential, with the middle, ring, and pinkie fingers wrapped firmly around the handle. The pointer finger should be placed on the spine of the knife, while the thumb is positioned close to the heel edge of the blade to steady the strokes. When cutting through bones, downward pressure should be applied with the non-dominant hand to push the knife cleanly through.

Steel: Ginsan / Silver #3
Ginsan steel, also known as Silver 3 or G3 steel, is a type of stainless steel used in high-quality kitchen knives. It is appreciated for its ability to offer the traditional feel and sharpness of carbon steel while providing the corrosion resistance of stainless steel. Ginsan steel contains a moderate amount of carbon, chromium, and other alloying elements that ensure a good balance between edge retention and ease of sharpening. This steel is particularly favored for its fine grain structure, which allows for a very sharp edge, and its resistance to rust makes it a popular choice among professional chefs and home cooks who seek the performance of carbon steel without the maintenance challenges. Ginsan steel knives are known for their durability, ease of care, and excellent cutting performance, making them a preferred option for those looking for high-quality stainless steel cutlery.

Construction: Nimai - Stainless Clad

Nimai(Two Piece) is the Japan's traditional approach to the kitchen knife making, this construction method is typically found on knives with native Japanese origins like Yanagiba, Deba and Usuba. When constructing a Nimai knife, a piece of soft cladding metal will be placed onto a core steel, the two pieces of metal are then forgewelded and shaped into the knife.
The Nimai knives are usually sharpened in single-bevel fashion, with hardened core steel exposed on the flat/hollow-ground side and soft cladding warping over the other side and over the spin. The soft cladding offers support for the harder yet more brittle core steel so the knive can have a thin, sharp edge while have some overall strength. Since the single bevel Japanese knives usually don't have a secondary bevel, the combination of soft cladding and hollow-grind have made the sharpening process easier than Monosteel and Honyaki knives.
In recent years, knifemaker have been trying to utilize stainless claddings on the traditional Nimai knives, which were typically forged withcarbon steel. But unlike the Sanmai construction, the core steel will still be exposed on the hollow-ground side even the stainless cladding can protect the other side. The Stainless Clad Nimai knives seen on the market now would typically use a stainless core to pair with the stainless cladding, making the Nimai and traditional single bevel knives much more approachable for users who are interested in them.

Finish: Kasumi

A Kasumi finish refers to a traditional Japanese blade-finishing technique used on knives, particularly those made from a combination of soft iron and harder steel. The term "Kasumi" means "mist" in Japanese, aptly describing the hazy, matte appearance achieved on the blade's bevel where the two metals meet. This effect is not only aesthetic but also showcases the craftsmanship involved in blending these materials, highlighting the skill in creating a knife that is both beautiful and functional.
