Arare (霰, Small Hail) is a fitting name — looking at the blade, the surface of the Hira is covered in a dense field of small, geometric square and diamond-shaped indentations with defined, sharp edges arranged in a tight repeating pattern. The texture meets the Shinogi line where it gradually fades as the bevel thins out during grinding and polishing, leaving the Migaki finished bevel below in clean contrast with the textured Hira above. It's a more considered and refined take on Tsuchime than the organic, irregular hammer marks you'd typically find, and if the pattern looks familiar, it's not a coincidence — a very similar texture appeared on a special edition of the Minamo SG2 line, which hints at a shared manufacturing origin, likely somewhere within the Takefu Knife Village network that Shibata has strong connections to.

The line is curated by Shibata, and the execution reflects his priorities clearly. The spine sits at a slim 2mm, paired with a concave grind that brings the bevel down to a low thickness behind the edge. Food release is handled by the Shinogi line — as the slice reaches that geometrical transition the food peels away cleanly, and the concave geometry keeps the thickness low enough that the knife doesn't wedge badly even in denser produce. It's a well-balanced geometry that performs beyond its price bracket and now competing for the best value knife we are currently selling.

The core steel is SG2 (also known as R2), one of the most capable powder stainless steels in the industry — excellent edge retention, full stainlessness, and a hardness that supports the thin geometry well. At 299 AUD for a 210mm Gyuto, this is genuinely exceptional value for an SG2 knife with this level of finish and sharpening behind it, sitting at a lower price than the Ryuhyo line while offering an arguably more characterful surface and comparable cutting performance.

Pros Cons
  • Budget friendly
  • Excellent performance
  • Ideal entry point to Japanese knives
  • A little bit brittle
  • Relatively hard to sharpen
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.

    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: Tsuchime
    Finish

    Tsuchime

    The "Tsuchime" finish in Japanese kitchen knives refers to a distinctive hammered texture on the blade's surface. This traditional technique not only adds a unique aesthetic appeal but also provides practical benefits, such as reducing drag and preventing food from sticking to the blade during slicing. It's a hallmark of craftsmanship that blends functionality with artistry, making each knife not only a tool but a piece of art.

    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.
