The Hatsukokoro by Myojin Shirasagi(白鷺)Blue 2 Kurouchi single bevel is a line of "practical single bevel" knives produced by Myojin Riki Seisakusho and comisioned by Hatsukokoro. It has a twin sister line Shirasagi White 2 that offers a different look made by same maker. If you are not familiar with Myojin is a father and son knife workshop based in Tosa prefecture, in the island of Shikoku. Father Tateo, is specialised in single bevel knife sharpening, whereas son Naohito Myojin specialises in double bevel knife sharpening, and Toru Tamura is their primary blacksmith.

This line as a single bevel line, is sharpened by Tateo Myojin(明神 健) and forged by Toru Tamura(田村 徹). Rarely, you can find not only the traditional profiles like yanagiba in this line, but also modern shapes like gyuto, all made in single bevel fashion. The fit and finish is superb as expected from Myojin Riki Seisakusho, a very uniform finish can be seen across the entire blade, even on the Kissaki of the Sakimaru Yanagiba, some other knives at higher price can have some trouble achieving that. Hatsukokoro have given this well-finished line a well deserved name Kirasagi(Little Egret), the smooth polish working in conjunction with the Kurouchi finish, match the elegant white feather and dark beak of egret perfectly.

This line can be an opportunity for those who are interested in the experience of owning a single bevel knife, but found the Yanagiba, Deba and Usuba being too job-specific. Having a single bevel gyuto will give you an idea of how single bevel blade works, while not restrain you with what could be cut with it. In addition, the combination of Kurouchi and carbon steel will offer some level of rust protection while maintain that authentic carbon steel "cutting taste"

That being said, the single bevel construction does make these knives quite thicker than typical knives of same size and shape. This not only makes the knives heavier, but also create more resistance when cutting into denser food like potatoes. However, the traditional single bevel knives in this line still have great value, with great fit and finish that are found on any blade sharpened by Myojin Riki Seisakusho, the Kurouchi finish and light Tsuchime pattern can make this line an interesting alternative to the typical shiny silver Yanagiba/Deba with quite a lower price. If you want that traditional look, the twin sister line Shirasagi White 2 line will off you the same level of craftsmanship.

Pros Cons
  • Budget friendly
  • Excellent fit and finish
  • Prone to rust
  • Heavy
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

Myojin Riki Seisakusho, a Tosa knife workshop

Myojin Riki Seisakusho (明神利器製作所) is a knife workshop in Uranouchi, Susaki, Kochi. It is headed by Naohito Myojin, son of Tateo Myojin.

Kochi City's page on Tosa crafts describes the workshop as carrying work from forging to finishing in one continuous process. The page says it sharpens a hamaguri-ba (蛤刃) edge, ground convex, a technique learned through several years of training in Fukui, and that it also takes sharpening-only orders from outside Kochi Prefecture.

Among the lines we list, the Hatsukokoro x Myojin Shirasagi single-bevel knives cover Blue 2 kurouchi yanagiba, K-tip yanagiba, sakimaru yanagiba and honesuki, White 2 deba, left-handed mioroshi deba, left-handed yanagiba and honesuki, and a Ginsan yanagiba. We also list Myojin Cobalt Special gyuto, santoku and bunka.

Knife details

Frequently asked questions

What is a honesuki for?

A honesuki (骨スキ) strips meat from the bone, the job a boning knife does elsewhere.

One Japanese knife maker describes the traditional honesuki as a shape unique to Japan, made with Japanese knife techniques and ground single-bevel (片刃), so it can also be used to prepare fish.

Can left-handed cooks use single bevel knives?

A standard single bevel knife is ground for right-handed use, and a left-handed one is made with the bevel reversed. Some makers offer left-handed versions.

Contact us and we will check what we can order or have in stock.

Will a carbon steel knife rust, and how do I look after it?

Yes, carbon steels such as Aogami (Blue) and Shirogami (White) are not stainless steels, so left wet they can spot or rust.

Care is simple once it becomes habit. Wipe the blade as you go, especially after acidic food like citrus, tomato or onion. When you finish, wash it in warm water with a little soap and dry it straight away with a towel. Do not let it air dry, leave it in the sink or the dish rack, or put it in the dishwasher. Store it dry: on a magnetic strip, in a saya or in a block in a dry spot.

If the knife will sit unused for a while, wipe on a thin layer of oil before storing. In our video James shows that mineral oil can stand in for camellia (tsubaki) oil, and he picks one labelled medical grade; we list the Kitchen Knife / Cutting Board Mineral Oil Medical Grade for this. If you find light rust, lift it with a rust eraser and a little water, then dry and oil the blade; we list the CKK and Naniwa rust erasers.

What is the difference between Blue 2 and White 2 steel?

Proterial lists 1.05 to 1.15% carbon for both steels; its Blue 2 table lists 0.20 to 0.50% chromium and 1.00 to 1.50% tungsten, while its White 2 table lists neither.

Proterial describes White 2 as a carbon steel with minimum impurities and high hardness, and Blue 2 as an alloy steel with tungsten and chromium to improve heat-treatment properties and wear resistance, with a hardening hardness of over 60 HRC for both. Neither steel is close to the JSSA's 10.5% minimum for stainless.

What does a Myojin Riki hamaguri-ba (clam) edge mean?

A hamaguri-ba edge, written 蛤刃, is a convex edge shape, and it is the shape the workshop 明神利器製作所 sharpens its knives to. Kochi City's craft page records that Myojin Riki learned it over several years of training in Fukui.

The same page says the workshop also takes sharpening-only orders from outside Kochi.

Does Myojin Riki forge its own knives?

Yes. Kochi City's craft page for his workshop 明神利器製作所 says the work runs from forging through finishing in one continuous process, 鍛造から仕上げまで一貫して行う.

That page lists the workshop in Susaki, Kochi.
