The Nigara SG2 Matt Migaki Kurouchi Tsuchime line is the twin sister of the non-Kurouchi finished line produced by Nigara. Their shared, optimised production procedures allow them to be offered at a very competitive price without sacrificing much performance. These blades are for those who are looking for a more durable powder stainless steel edge, but also like the rustic look of the Kurouchi. As far as I know, this isn’t a common combination on the market, not to say that Nigara offer a whole series of different sizes and profiles in this line.

Being the most commonly used powder stainless steel in the Japanese kitchen knife industry, the SG2/R2 holds its place steadily with a good combination of toughness, edge retention and corrosion resistance. However, to get you hands onto this steel would be bit costly. Tojiro offers a series of SG2 knives from their budget DP series, Hatsukokoro also have a SG2 member in their Hayabusa family that comes at even lower price. However, the hand-grind bevel by Nigara’s skilful sharpener offers their knives a much more optimised geometry, beating Tojiro and Hatsukokoro with a better overall cutting performance while costing only a slightly more.

The fit and finish is consistent as usual for these Nigara blades. Good surface consistency, straightness and sharpening. The Kurouchi gives a completely different look to its twin sister line, making these knives a bit more popular choice for gifting. I have to be honest, this layer of black finish seems to be painted on instead of formed during the heating of the blade, but it is understandable as the stainless cladding doesn’t require the corrosion resistance of this oxidation layer, and is seems to be hard to form a dark Kurouchi finish on surface of the high alloy stainless steel.

Overall, Nigeria’s SG2 Matt Migaki lines are successful blades that excel in performance at their price bracket, the addition of the Kurouchi finish allows even more characterful selections for buyers and indeed we found many customers of us favour this more rustic look. We recommend this line to those whole want to upgrade their steel from the more entry level steels like VG10/AUS10, and to beginners who have a bit more budget as the sturdiness of the thicker bevel can help with reducing the chance of chipping.

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

Santoku

The Santoku(三徳) knife, embodying the meaning "three uses," is a cornerstone in Japanese kitchens, adept at slicing, dicing, and mincing. Esteemed for its versatility, it features a blade length typically between 15cm and 20cm (6 to 8 inches), catering to a wide array of culinary tasks. Distinguished by its less pointy tip compared to the Gyuto, the Santoku boasts a unique profile that contributes to its functionality and popularity. Its design is more controllable in chopping and slicing, and the profile is less aggressive, for those reasons, it has bacame a preferred choice for home cooks.

Nature Stainless
Hardness62–64 HRC

SG2, also known as Super Gold 2 or R2 steel, is a high-end powdered tool steel by Takefu Special Steel, known for its excellent edge retention, wear resistance, and ability to achieve a hardness of up to 64 HRC. Identical to Kobelco Steel's R2, it's prized in premium knife making for its fine edge sharpness and durability. The powdered nature ensures uniform carbide distribution, enhancing toughness and reducing chipping risks. SG2/R2 is ideal for those seeking top performance and longevity in their cutting tools.

Construction

Sanmai - Stainless 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.

The soft cladding enables the thinning process to be a lot easier than a honyaki or monosteel construction. And in the case where the cladding steel are stainless in nature, it can offer protection for the carbon or semi-stainless cores against rusting and discoluoring.

Finish

Kurouchi Tsuchime

The Kurouch Tsuchime is a combination of the raw, organic black finish and the characterful hammered Tsuchime finish. It is commonly seen as the Kurouchi finish will keep the original black scale of the billet unpolished after forging, the texture from the forging process will be also kept, allowing all kinds of patterns and indentations to be introduced to the blade. As a combination of Kurouchi and Tsuchime, this finish also inherents their benifits: reduce drag, help with food release and protect the steel from rusting. Over all Kurouchi Tsuchime is a practical and esthetically unique finish.

Handle

Octagonal Ebony

Profile Octagonal WA
Material
- Ebony

This handle, crafted from a single piece of ebony, exemplifies minimalist elegance and functional design. Its unique octagonal shape, featuring a subtle taper, offers a comfortable grip and a visually appealing geometric profile. The ebony wood, known for its deep, rich color and durability, has been meticulously milled from a single block, ensuring a seamless construction that highlights the wood's natural beauty and grain. The handle's surface has been highly polished, achieving a glossy finish that not only enhances the ebony's luxurious dark hue but also provides a smooth, tactile experience for the user. This design choice reflects a minimalist approach, focusing on simplicity, quality, and usability. The combination of the octagonal shape with the taper adds a modern twist to the classic material, making it a standout piece that blends traditional craftsmanship with contemporary aesthetics.

Frequently asked questions

Gyuto or santoku - which should I choose?

Both are all-purpose Japanese knives, and for most home cooks either will handle the bulk of daily prep. The choice comes down to length, blade shape, and how you like to cut.

A gyuto is the Japanese chef's knife - typically 210 to 240mm with a gently curved edge that lets you rock and slide through cuts as well as chop. The extra length and pointed tip give you reach and versatility, from proteins to large produce.

A santoku is shorter, usually 165 to 180mm, with a flatter profile and a rounded sheep's-foot tip. It rewards a straight up-and-down push cut, feels nimble in smaller hands or tight kitchens, and is the classic Japanese household knife.

Rule of thumb: choose a gyuto if you want one do-everything knife with more reach, or a santoku if you prefer a compact, easy-to-control blade. Plenty of our customers end up owning both.

SG2 steel knives at Knives and Stones

SG2 is my go-to recommendation for anyone who wants a stainless knife that performs like carbon steel without the fuss. At 1.25% carbon and HRC 62-64, it takes a screaming edge and holds it far longer than VG-10 or AEB-L, all while being fully rust-resistant. You get the best of both worlds: no patina worry, but real cutting performance.

SG2 vs AS steel for kitchen knives — which is better?

Neither is objectively better, it just depends on whether you value stainless convenience or a laser-sharp carbon edge. Go with SG2 if you want a knife that holds a screaming edge without any babysitting. Choose AS if you are chasing the thinnest possible edge and don't mind wiping the blade down after every use.

SG2 is a powdered stainless steel from Takefu, usually sitting around 62-64 HRC. It is tough and resists corrosion, which is why I reach for it when working with acidic foods. Aogami Super is high carbon and typically harder at 64-66 HRC. It sharpens to a hair-whittling edge that lasts slightly longer than SG2, but it will rust if you neglect it.
