The Nakagawa Blue 1 Damascus Etched/Kurozome Wide bevel is Satoshi Nakagawa's classic wide bevel knife with a twist in finish. When talking about Sakai, most of the knife enthusiasts will think about well polished blades with prestige Migaki or Kasumi finish that comes in all kinds of metallic silver colour. This Kurozome is an interesting attempt to utilize the contrast created with etching to highlight the geometry created by the wide bevel finish. As the result, we see a very polished Sakai knife that look like Kurouchi from afar, but very tame if inspected closely.

One thing with Nakagawa-san's knife is that his Damascus gyuto seems to be a bit thicker than the Sanmai ones, but thanks to the well-done concave grind, these blades stays very thin behind edge and still cuts beautifully. Additional material above the primary bevel adds some weight and rigidity to the blades, if you are in favor of knives with solid handling, this line will easily fall into that category.

The level of finish is still Sakai standard, chamfered choil and spine are all polished with a good shine. But the etching is really the highlight of these knives: the two different steel in the damascus cladding react differently with the acid, leading to a well aged look composed of intertwining brown and blue colour. This vintage finish contrast strongly with the Migaki finished bevel and buffed spine at the clearly defined boundary, rounding these knives up with a sharp geometrical look.

I say this a is an interesting finish, and it's always nice to see Sakai makers to be innovative with their finishing technic and pushing boundaries. The main drawback of these knives might be the level of care required for them, as both the soft i on Damascus cladding and the core steel are prone to rust. But if you are interested in a beautifully finished knife with a lots of hand crafting goes into it, please do consider this blue 1 Damascus line.

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.
Oil the (carbon) knife if storing for an extended period of time to prevent rust.

Satoshi Nakagawa Hamono - Sakai's New Power House (Est. 2021)

Nakagawa Hamono, established by Satoshi Nakagawa (中川悟志) in April 2021, carries on the legacy of the renowned Shiraki Hamono under the guidance of Nakagawa-san, a dedicated disciple of the legendary craftsman Kenichi Shiraki. With nearly two decades of experience, primarily under Shiraki-san, Nakagawa-san has been instrumental in creating some of the finest honyaki blades in the last five years of Shiraki-san's work.

His expertise is not limited to Shiraki Hamono’s offerings but extends to forging top-tier knives for Sakai’s esteemed brands such as Sakai Takayuki, Kikumori to name a few. Based in Sakai City, Osaka, Nakagawa Hamono specializes in Ginsan and blue steel knives with wide bevels.

Satoshi Nakagawa Hamono was founded in April 2021 by Satoshi Nakagawa, a skilled craftsman from Sakai City, Osaka, who embarked on his journey into the world of knife-making at the tender age of 18. After high school, he was introduced to Kenichi Shiraki, a legendary master craftsman, and subsequently joined Shiraki Hamono. Under Shiraki-san's tutelage, Nakagawa-san honed his skills for nearly two decades, playing a pivotal role in the creation of many of Shiraki-san's renowned works, particularly in the latter years. His expertise extends to forging exclusive knives for prestigious Sakai retailers such as Sakai Kikumori and Sakai Jikko, showcasing his mastery across various top-tier lines.

Upon the retirement of Kenichi Shiraki, Nakagawa-san assumed leadership of Shiraki Hamono, now rebranded as Nakagawa Hamono. This transition marked the continuation of a storied legacy, with Nakagawa-san bringing his innovative vision to the fore. His current offerings are primarily forged from Ginsan steel, known for their distinctive wide bevels, with plans to expand the range to include diverse profiles and steels. Nakagawa-san's approach to knife-making is deeply rooted in tradition yet forward-looking, embracing new materials and trends while preserving the manual, labor-intensive processes that define the craftsmanship of his knives. His work on crest forging with blue steel No. 2 and No. 1 is a testament to his commitment to beauty and excellence, despite the challenges and heartbreaks encountered in the painstaking process of honyaki forging. Nakagawa Hamono stands as a beacon of traditional craftsmanship, blending timeless techniques with contemporary innovation, under the stewardship of one of Sakai's most promising craftsmen.

“Sakai's leading blacksmith of the new generation. ”

Profile

K-tip Gyuto

Chefs Knife

The K-tip Gyuto — known in Japanese as kiritsuke gyuto (切付牛刀) — is a double-bevelled chef's knife that pairs the all-purpose body of a standard gyuto with a kiritsuke-style tip: an angled, clipped "k-tip" point in place of the gyuto's curved belly. Combined with a flatter edge profile, this gives two advantages. The sharply defined tip excels at precise work — scoring, detailing and picking — while the flatter edge is optimised for clean push-cutting and long slicing strokes. It remains a versatile general-purpose knife, but rewards a chef who works with deliberate, tip-led precision.

A note on naming: the K-tip (or "Kiritsuke") Gyuto is a double-bevelled knife and should not be confused with the traditional Kiritsuke (切付け) — a single-bevelled knife that is a genuinely different tool. Many retailers list the two interchangeably; at Knives and Stones we keep them distinct so you know exactly what you're buying.

Nature Carbon
Hardness61–64 HRC

Blue Steel No.1, also known as Aogami #1 or Yasugi #1 Blue Steel, is a premium high carbon steel from Hitachi Metals Ltd, celebrated for its exceptional edge retention and toughness. This steel is an upgrade from Blue Steel No.2, enriched with higher carbon and tungsten content, making it a favorite for high-grade Japanese traditional single-bevel knives. It's known for being easy to sharpen, achieving a very fine edge that lasts. Despite its susceptibility to rust, with proper care and maintenance, including regular wiping and drying, it can develop a protective patina that minimizes rusting. Blue Steel No.1 is highly regarded among knife makers for its ability to achieve a mirror finish and maintain a sharp edge over extended periods, offering an outstanding balance of performance and durability.

Construction

Sanami - Soft Iron Damascus Clad

Sanmai (Three-Piece) is a common construction for double bevel knives where two pieces of softer cladding steel are forgewelded to each side of a harder core steel. The harder but more brittle core steel will form the hard cutting edge after heat treating, and the softer cladding will support the core to increase the overall strength of the blade.

Damascus Sanmai utilize damascus steel as the cladding material for the Sanmai construction, which adds aesthetic feature to the blade. However, the damascus cladding found on Japanese kitchen knives with carbon steel core are ususally made of soft iron, which means they too need to be maintained to stay pretty.

The soft cladding enables the thinning process to be a lot easier than a honyaki or monosteel construction. However, when the cladding is made of damascus, whether etched, polished or mirror polished, the thinning process will take a toll on the cladding, meaning the damascus won't look the same as when it was taken out of the box.

Finish

Etched

The etching process starts with the knife being thoroughly cleaned to remove any oils or residues. A protective mask may be applied to the areas not intended to be etched. The blade is then submerged in an acidic solution, such as ferric chloride, which reacts with the different layers of steel at varying rates. This creates a layer of dark oxide on the surface of the blade where the thickness of the oxide varies according to the reactiveness of the steel. After etching, the knife is neutralized in a baking soda solution, rinsed, and dried. The final step involves polishing the blade to highlight the etched design, enhancing both the knife's beauty and showcasing the craftsmanship of its maker.

Handle

Octagonal Birch Burl with Spacer

Profile Octagonal WA
Material
- Birch Burl Stabilized

The stabilized birch burl handle adorning the Hatsukokoro chef knife is a testament to both exquisite craftsmanship and natural beauty. Birch burl, prized for its intricate grain patterns and unique textures, undergoes a meticulous stabilization process to enhance its durability and stability, ensuring longevity and resilience against moisture and wear.

The handle's ergonomic design offers a comfortable and secure grip, allowing for extended periods of use without fatigue. Its smooth contours and balanced weight distribution contribute to precise control and effortless maneuverability during culinary tasks.

The natural variations in color and grain of the birch burl create a visually captivating aesthetic, making each handle distinctively unique. This harmonious blend of functionality and aesthetics not only elevates the chef knife's performance but also adds a touch of elegance to the kitchen, reflecting the unparalleled craftsmanship of Hatsukokoro knives.

Frequently asked questions

Is a K-tip Gyuto the same as a traditional Kiritsuke?

Not quite - and it is the single most common point of confusion when people shop for a kiritsuke. The two knives share the same striking angled, reverse-tanto tip, but underneath that tip they are very different tools.

A K-tip gyuto is a double-bevel knife: it is ground on both sides like any Western-style chef's knife, so it is ambidextrous, forgiving to use, and sharpened exactly the way you would sharpen a normal gyuto. You get the dramatic kiritsuke look with the everyday usability of an all-purpose chef's knife.

A traditional kiritsuke - including the kiritsuke-yanagiba (slicer) and kiritsuke-gyuto shapes - is a single-bevel knife, ground on one side only. It is historically a master chef's knife: it takes real practice to use well, is set up for right-handed users by default, and needs single-bevel sharpening technique to maintain.

So if you want the kiritsuke silhouette with no learning curve, choose a K-tip gyuto. If you specifically want the traditional single-bevel discipline - and the precision it allows on fish and vegetables - choose a true kiritsuke. At Knives and Stones we stock both, and each product page tells you which construction you are looking at.

Will a carbon steel knife rust, and how do I look after it?

Yes - carbon steels such as Aogami (Blue) and Shirogami (White) react with food, moisture, and acids. Left wet they can spot or rust, and with normal use they develop a grey-blue patina. That patina is expected and is part of owning a carbon-steel knife; it is not damage.

Care is simple once it becomes habit: hand-wash in warm water, never leave the knife soaking or sitting in a wet sink, and dry it thoroughly the moment you finish. Avoid the dishwasher entirely, and wipe the blade between tasks when you are cutting acidic foods like citrus, tomato, or onion.

If the knife will sit unused for a while, wipe a very thin film of food-safe camellia oil (or a neutral mineral oil) onto the blade before storing it. A light surface rust spot lifts easily with a rust eraser or a little Bar Keepers Friend; sustained neglect is the only thing to really avoid.

Carbon steel rewards this small amount of attention with a keener edge and easier sharpening than most stainless. If you would rather not think about maintenance at all, ask us about stainless or stainless-clad options instead.
