    Tanaka’s SG2 Kurozome Damascus is the top end product offered at Tanaka Kazuyuki Hamono. This excellent design combines high performance geometry, beautiful finish with Tanaka’s signature profile to create a highly functional yet good looking knife, and when it’s paired with the best handle in the industry crafted by Nishihara Sadao, it can easily be a top shelf item chased by collectors and enthusiasts.

    Tanaka’s knives have always been known for their tall heels, and this line is no exception. Gyuto usually has heel height of at least 50mm, even 150mm petty can get a measurement of 33mm at the heel. The tall heel translates into a broad blade, it is more stable when pushing through denser produce and requires a smaller range of motion when doing rocking chopping, additionally, like a chinese cleaver, the wide blade is very good in picking chopped food up and transferring it to another container.

    These SG2 are forged quite thin and finished in a gradual convex grind, a construction that is familiar to a lot of experienced knife nerds. Names like Shiro Kamo Takeshi Saji or Takamura would come across your mind when you pick up these knives, and it is not a surprise as Tanaka san did earn his skill in the Echizen region. This is a design that is well tested by time, based on a dazzling Damascus clad SG2 billet, an etching process turns layered steel into contrasting pattern, the additional friction created by this slightly rough finish is mitigated by an outstanding geometry, the convex in the blade is strong enough to push the sliced food off the surface and reduce friction but thin enough to cut into dense roots without excessive wedging. This knife is a good match with Kamo san’s Kurokumo or Takamura’s Uchigumo.

    The handle is something worth mentioning too. In some occasions, these blades will be fitted with a synthetic handle or a WA handle, but at KnS, most of Tanaka’s SG2 comes with ironwood western style handles fitted with mosaic pins. These handles mould into your hands with excellent geometry and smooth finish, the master behind these handles Nishihara Sadao have been the top maker in this craft for many years. He is at a semi-retirement stage at an age over 80, so any of these handles made by him would be increasingly harder to acquire. These accumulated experiences speak for themselves, as soon as you put a bit of force into your hand, the handle will automatically slide and lock into a perfect spot for a pinch grip. Desert Ironwood as the premium material for knife handles has great stability without stabilization process, and once they are polished properly, the revealed texture and colour can rarely be matched by any other timbers.

    Pretty knives like these usually don't come in a pretty price, and the Ironwood handle lineup we stock usually price at 4 digits, I think a petty that is close to a thousand AUD would make anyone take some considerations before making a final decision. Is it worth it? This is a question that I think you would need to ask yourself when thinking about these knives. Regardless of the price, this is still a line that has great functionality due to its choice of material, finish and sharpening. 

    Pros Cons
  • Excellent performance
  • Great artistic
  • Excellent fit and finish
  • 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.

    Shigeki Tanaka

    Crafted in Miki City, Hyogo—Japan’s historic blade-making heartland—Shigeki Tanaka knives embody generations of blacksmithing expertise. Known for their exceptional sharpness and balance, these blades are forged using high-carbon steel (like Aogami #2) and traditional techniques, ensuring outstanding edge retention. The brand’s signature kurouchi (blacksmith’s finish) gives each knife a rustic, hand-forged look while protecting the blade.

    Tanaka’s knives are favored by chefs and collectors for their precision, durability, and exceptional performance. Many feature elegant wa (Japanese-style) handles made from magnolia or ebony, along with his signature Bob loveless inspired coke-shaped western ironwood handle, designed for comfort and control. With a focus on pure craftsmanship over flashy aesthetics, Shigeki Tanaka delivers professional-grade blades that honor Hyogo’s samurai sword-making legacy.

    • Profile: Petty

      Utility, Paring

      The Petty knife, a smaller Japanese utility knife, serves as an ideal tool for precision tasks such as peeling, trimming, and slicing fruits and vegetables. With a blade length ranging from 120mm to 180mm (4.7 to 7 inches), it stands out for its ability to handle detailed work like deveining shrimp or cutting garnishes. Its slightly longer and slimmer profile compared to the Western paring knife enhances its functionality for intricate tasks, making it a valuable addition to any kitchen toolkit.

    • Steel: SG2 / R2

      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 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. On the Kitchen knives with stainless core steel, the damascus cladding will be stainless, this means they will also protect the carbon/semi-stainless core from rusting/discolouration.

      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.
