    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.
    7. Oil the (carbon) knife if storing for an extended period of time to prevent rust.

    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: Nakiri

      The Nakiri 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 characterized by its relatively flat edge profile, designed specifically for a chopping motion ideal for vegetable preparation. Unlike knives intended for slicing or sawing motions, the Nakiri's design emphasizes straight, clean cuts through vegetables without the need for pushing or pulling. Its blade is notably thin, underscoring its specialization for tasks that do not involve contact with bones, even small ones. This specialization makes the Nakiri an indispensable tool for those seeking precision and ease in vegetable preparation.

    • Steel: Blue 2 / Aogami #2

      Blue Steel No.2, also recognized as Aogami No.2, is a distinguished high carbon steel produced by Hitachi Metals Ltd, enhanced by the addition of chromium and tungsten to the base of White Steel No.2. This modification brings about an improvement in toughness and the creation of hard carbide molecules, which significantly boost edge retention. Although its sharpness is comparable to that of White Steel No.2, Blue Steel No.2 offers a slight advantage in maintaining its edge.

      Widely favored for its versatility, Aogami No.2 is celebrated for its ease of sharpening and robust resistance to chipping, making it an ideal choice for those new to Aogami steel knives. Containing 1.0–1.2% carbon and achieving a typical hardness of 62–63 HRC on the Rockwell scale, it stands as the benchmark in evaluating Aogami steel cutlery.

    • Construction: Sanmai - Soft Iron Clad

      Sanmai iron cladding is a traditional Japanese knife construction technique where a hard steel core is sandwiched between two layers of softer iron or steel. This method combines the superior edge retention and sharpness of high-carbon steel with the durability and ease of maintenance provided by the softer outer layers. The sanmai structure offers a balanced knife that is both flexible and resistant to breaking, ideal for precision cutting tasks. The softer outer layers also facilitate easier sharpening and contribute to the aesthetic appeal of the knife through the development of a unique patina over time. While sanmai-clad knives require careful maintenance to prevent rust, their exceptional performance and distinctive appearance make them often a desirable feature of Japanese knives.

    • 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.

    ======

    Naohito Myojin (明神 直人) is a young sharpener based in Kochi prefecture. While his workshop Myojin Riki Seisakusho is probably not as famous as the established brands from Sakai and Echizen, he is the sharpener behind some of the very famous knife lines in the industry; noteabley the Tetsujin brand and the 'Fujiyama' line by Konosuke. 

    Naohito Myojin Sharpening

    I think 'refined' is the best word to describe Naohito's work: while featuring proven cutting performance, his knife has some of the best finishes out there. The spine is nicely chamfered, choil is well polished. By engraving his name Naohito on to the knivves, you can tell that he must be really proud of his work, and I trust you will enjoy his knife as well.
