The Hatsukokoro Hayabusa ATS34 Sanmai series features premium ATS-34 steel, an upgraded version of 440C with added molybdenum, offering exceptional hardness, edge retention, and durability. Identical to the classic 154CM steel, it ensures a long-lasting, razor-sharp edge.

Crafted with a clean sanmai construction and a refined migaki finish, this knife embodies simplicity and elegance while maintaining excellent cutting performance. The ATS34 Hayabusa have a slightly different profile than other members from the Hayabusa family, their curved tip provided a more rounded "belly", making it much easier to perform rock cutting with these knives.

Pros Cons
  • Budget friendly
  • Easy to look after
  • Fit and finish can be improved
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.

Hatsukokoro

Hatsukokoro, a knife brand from Amagasaki

Hatsukokoro (初心) is a knife brand from Amagasaki, Hyogo, launched in 2019. It is a brand rather than a forge: it works with knife makers instead of forging itself.

The name comes from the proverb 初心忘るべからず, roughly never forget your beginner's mind. For the same characters the brand chose the gentler reading hatsukokoro over shoshin.

The brand's own catalogue names the place behind some of its lines, and the maker behind a few: Shinkiro comes from Fukushima, and Hayabusa HAP40, Saihyo and Sunaarashi from Seki City, while for others the maker or the place stays private. Some of our listing titles also carry the maker alongside the brand, such as Hatsukokoro x Yoshikane and the Hatsukokoro x Yoshihiro Yauji collaboration.

The Hatsukokoro lines we list include both carbon and stainless steels. Our listings include Hayabusa in SG2 and Aogami Super, Saihyo in SG2 and Ginrei in Ginsan. Carbon steel kurouchi lines include Aosagi, Aokitae, Kurokaze and Kurogane.

“A knife brand from Amagasaki that works with knife makers rather than forging.”

Frequently asked questions

Why is it called a bunka knife?

The bunka knife (文化包丁) takes its name from bunka, culture. A Sakai knife maker ties the name to Japan's modernisation, when Western culture and Japanese tradition merged, and says it stands for that new era and for the knife's wide range of uses.

The same maker says that as diets broadened to meat, fish and vegetables, an all-purpose knife was wanted, and the bunka took features from both Japanese and Western knives.

What is the difference between a bunka and a santoku?

The tip. One Japanese knife maker describes the bunka (文化包丁, kengata) as combining the good points of the gyuto and the nakiri with the tip cut at an angle, and the santoku as coming after it, by rounding that tip.

Both are all-purpose knives for the home; santoku (三徳) means three virtues, for the three foods it cuts: meat, fish and vegetables.

Who makes ATS-34, and is it stainless?

Proterial makes ATS-34, a stainless blade steel. Its YSS page describes it as one for custom knives and high-quality cutlery tools, listing 14.00% chromium and 4.00% molybdenum and keeping the carbon figure closed.

That chromium is above the JSSA's 10.5% minimum for stainless steel, and the association notes that stainless, strictly, means it rusts less. Wash the knife and dry it after use.

Is Hatsukokoro a maker or a brand, and who makes the knives?

Hatsukokoro (初心) is a brand, not a forge. H&K, a company founded in 2013 and based in Amagasaki, Hyogo, created it in 2019.

H&K names the producer for some lines, for example Shinkiro by Takahiro Nihei in Fukushima, Ginyou by Yoshihiro Yauji in Echizen and Kurosagi by Motokyuichi Hamono in Nagasaki, and keeps others confidential. Some knives we stock carry the maker in the title, such as Hatsukokoro x Yoshikane SKD Nashiji.

What does the name Hatsukokoro mean?

The name comes from the Japanese proverb 初心忘るべからず, which means don't forget your original intention. The company read it gently as hatsukokoro rather than shoshin.

H&K created the brand in 2019, six years after the company was founded, and chose the name for its knife line.

Which Hatsukokoro line should I pick, carbon or stainless?

Pick by how much care you want to give. The carbon lines, Blue 1, Blue 2 and AS kurouchi, need drying and a little oil after use. The SG2, HAP40, Ginsan and VG10 lines are low maintenance, so they suit a busy kitchen or someone who just wants to cook.

Neither is better; it depends on your routine. If you will dry and oil the blade after each use, a carbon line can suit you, and if you want the least fuss, a stainless line is the easier choice.
