This is a line up of knives produced by Nigara have excellent performance  for how much they cost. Just like their well known VG10 line, these blades employed optimised fabrication procedures, allowing users to obtain a combination of sharp edge geometry and a powder stainless steel edge at a very acceptable cost.

The SG2/R2 being the most commonly used powder stainless steel in the Japanese kitchen knife industry can offer a reliable toughness and edge retention. However, the higher cost of the steel means it’s usually hard to get knives made with it under 350 AUD(210mm Gyuto). The SG2 Hayabusa produced by Hatsukokoro offers a very low price for those who want to experience this steel and its ability to hold its edge, but the Matt Migaki Tsuchime line from Nigara would have a better sharpness and food release due to its hand-sharpened, sabre grind concave edge geometry. 

The overall fit and finish is just like other knives produced in similar fashion by Nigara, you can expect very consistent surface condition, straightness and rigidity throughout different profiles. The soft stainless cladding has a very pretty smooth matt finish while the core steel still has parallel polish marks left from Migaki finish. Compare to the VG10 line with Damascus cladding, this is a very simple yet elegant design, if you are looking for a slightly different look, there is a twin sister line by Nigara that comes with Kurouchi finish. 

The slightly thicker thickness of the blade gives the knife more sturdiness, combining with the ease of maintenance,  it allows this lineup of knives to be an excellent starting point for those who want to get into Japanese knife with have a bit more budget. And for the VG10 users looking for an upgrade, these blades offer better core steel with only a slight increase in price, but more importantly maintain a very good fit and finish and sharpness.

Pros Cons
  • Excellent performance
  • Easy to look after
  • 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.

Hirosaki sword and knife artisan

Based in the small yet beautiful city of Hirosaki in the northern prefecture of  Aomori, Nigara hamono has been making samurai swords for 350 yearas, with master Kunitoshi  (國俊) being one of the most famous sword smith in his generation. Now headed by the 8th generation mastersmith Go Yoshizawa (吉澤 剛) supported by his father Toshiju Yoshizawa (吉澤 俊寿), Nigara is becoming very popular thanks of its exquisite forging skills and second to none quality control. 

“Katana making family in Aomori carrying their linage with creativity and innovation, known for the striking "Anmon" design and striking high-end, hand forged damascus items”

Profile: Santoku
Profile

Santoku

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.

    14.0% 10.5% 7.0% 3.5% 0
    C Carbon 1.25%
    Primary hardening element. Raises hardness and wear resistance — but too much increases brittleness and corrosion susceptibility. As a reference: German 1.4112 (~0.5%) sits at the low end; VG-10 (~1.0%) is a common mid-range; SG2 (1.25–1.45%) and ZDP-189 (~3.0%) represent high and extreme ends respectively.

    Cr Chromium 14.0%
    Raises corrosion resistance; 13%+ qualifies steel as stainless. Also improves hardenability and wear resistance. In kitchen use, higher chromium levels contribute to a slight drag or sticking sensation when cutting — a trade-off for the rust resistance it provides.

    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
    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.
