    Myojin Riki Seisakusho as a father-and-son workshop is operated by Myojin family, the son Naohito is the sharpener and polisher of the double bevel knives in the workshop and the level of fit and finish achieved is top notch in the industry. Famous work that Naohito works on includes Konosuke Fujiyama FM series, the Tetsujin brand and some of the really rare blades forged by Hashimoto Shoichi. Aside from these collaborations, Naohito also keeps some personal lineups, which include a Ukiba Cobalt Special steel line and this Kasumi SG2 line.

    The sharpening approach for these SG2 knives are not nearly as aggressive as the Tetsujin knives, the bevel is a bit thicker, but is still in a very comfortable convex grind that would flow through most foods without much resistance. Although it would wedge more in very dense roots like carrot and sweet potatoes, but in a more succulent food like a fresh white potato, the stronger convex resulted from a thicker blade can encourage food separation, and I feel these SG2 is bit less sticky than the Tetsujin when dealing with these kind of food.

    The SG2 doesn’t need much introduction, it is still one of the best kitchen knife steels you can find without going to the steels that are impossible to sharpen. It scores pretty high in edge retention while being fully stainless, which makes a good material for professionals as it requires sharpening less frequently and doesn't need special care.

    The fit and finish is phenomenal, but also what you would expect from Naohito Myojin. The super consistent Kasumi finish covers the entire soft steel cladding, which just makes the polished core steel and spine pops out on the edge. Every sharp corner is cleanly chamfered and despite the crisp boundary between each surface, the choil and spine doesn’t feel sharp at all. This silky smooth Kasumi has just the right reaction when cutting food as it is not too rough to create friction and not too smooth to stick.

    As the Naohito Myojin is now recognised as the top sharpener of the industry, he is very caught up in all kinds of jobs, and being the only person working on these different projects, any of his knives would be highly sought after. This SG2 is one of those items and it has the best steel(edge retention wise), which makes it very hard to come by. Whether you are a collector, knife enthusiast or pro chef looking for a good tool, this line is something you would want to try out if the opportunities come by.

    Pros Cons
  • Excellent performance
  • Thin behind the edge
  • Excellent fit and finish
  • A little bit brittle

  • 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.

    Myojin Riki

    The Myojin Riki Manufacturing, established by a founder who mastered his skills in Osaka, the heartland of blade-making, has been operational for over 80 years. Specializing in knives made from steel and iron, they've recently focused on stainless steel knives, valued for their light weight, resistance to rust, and exceptional sharpness. These knives are popular among both professionals and general consumers, partly due to their application of the "stacked steel pattern" traditionally found in swords. The second generation continues to innovate, customizing products to meet users' needs, while also contributing to cultural preservation through their involvement with local traditional performances and blade repairs.

    • Profile: Gyuto

      Chefs Knife

      A Japanese chef's knife is known as a gyuto (牛刀 ぎゅうとう) gyūtō?), literally meaning 'beef knife'. Its blade resembles a flatter version of a French chef's knife. Japanese cutlery is known for sharpness due to its acute blade geometry, and the hardness of the steel used, sometimes exceeding 60 HRC on the Rockwell Scale A typical western chef's knife may be sharpened to an edge angle of 20-22°, while a Japanese gyuto generally has a sharper edge angle of 15-18° (or even lower), which requires a harder, more brittle grade of steel. In recent years Japanese gyuto have gained in popularity with western chefs.

      A modern chef's knife is a multi-purpose knife designed to perform well at many differing kitchen tasks, rather than excelling at any one in particular. It can be used for mincing, slicing, and chopping vegetables, slicing meat, and disjointing large cuts.

    • 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 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: Kasumi

      A Kasumi finish refers to a traditional Japanese blade-finishing technique used on knives, particularly those made from a combination of soft iron and harder steel. The term "Kasumi" means "mist" in Japanese, aptly describing the hazy, matte appearance achieved on the blade's bevel where the two metals meet. This effect is not only aesthetic but also showcases the craftsmanship involved in blending these materials, highlighting the skill in creating a knife that is both beautiful and functional.
