The Nigara SG2 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 performance. These Special Western handle Anmon are fitted with hand-shaped coke bottle profile ergonomic handles, often comes in unique and exotic materials, often contrast strongly with the rustic Kurouchi look of these blades.

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.

Pros Cons
  • Highly collectable
  • Excellent fit and finish
  • Great artistic
  • Heavy
  • High budget
Care Instruction
  1. Don't cut hard things! Japanese knives are brittle so bone hacking is a NO NO!
  2. Wash with neutral detergent after use, and wipe dry;
  3. Please don't wash knife with dishwasher, it will damage the wood handle;
  4. Be careful not to leave the knife close to a heat source for a long time;
  5. It is a lot more dangerous to cut with a blunt knife than a sharp knife!
  6. It is best to sharpen a Japanese knife regularly on a waterstone.

Knife details

Profile: Nakiri
Profile

Nakiri

Japanese Vegetable Knife

The Nakiri(菜切) knife is a distinctive tool in the Japanese kitchen, resembling a slender, shorter variant of a Chinese cleaver and serving as the household counterpart to the professional-grade Usuba. It is characterised by its relatively flat edge profile, emphasising straight, clean push cuts through vegetables without the need for rocking. This flat edge makes a full contact with chopping board when pushed down and it means there will be little to no chance of food still connect after the cut - a common problem with blade with very curved profile. Unlike Usuba, the thin and double bevel Nakiri is much better at penetrating dense and tough roots and tubers, Although sacrifices the ability to do delicate pinpoint slice, the rounded tip can give you a bit more sense of safety in operation.

    SG2 (Super Gold 2, also documented as SPG2) is a powder-metallurgy blade steel made by Takefu Special Steel. Takefu describes a fine, uniform structure and lists hardness of HRC 62 or higher. The maker's heat treatment determines the hardness of a finished knife. Takefu does not publish its current chemical composition; the ranges below are reference figures.
    Construction: Sanmai - Stainless Clad
    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
    Finish

    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.

    Frequently asked questions

    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.

    R2 steel vs SG2 — are they the same?

    Yes, R2 and SG2 are the same steel — R2 is the name used by Kobelco Steel, and SG2 (Super Gold 2) is the name used by Takefu Special Steel for the identical powdered metallurgy formula. The catalog confirms this: SG2 / R2 is a powder (PM) steel from Takefu Special Steel, Japan, with a composition of 1.25% carbon, 14.0% chromium, 1.8% vanadium, 2.3% molybdenum, and a hardness range of 62–64 HRC. So if you see a knife labeled R2 or SG2, you are getting the exact same material.
