Introducting the Hatsukokoro Ginga(銀河) ATS-34 line: an excellent steel forged by a highly talented young smith.

Hatsukorko, teamed up with Yoshihiro Yauji, one of the youngest Dentokogeshi (Traditional Craftsmen) in Takefu Knife Village, to create this beautiful line of knives that are extremely nimble yet tough enough to deal with every occasion in the kitchen. The high level of fit and finish is evident from the rounded and polished spine and choil, as well as the profile that tapers from heel to tip. The clean and uniform mirror polish across the entire blade not only displays the attention to detail, but also makes the damascus pop and shine, living up to its name Ginga(Milky Way).

The ATS-34 steel, manufacturerd by Hitachi Special Steel, is the Japanese equivalent of the 154CM, famous for its toughness, corrosion-resistance and "high-speed" properties. Bob Loveless brought the ATS-34 into fame in the 70s.

In recent years, the creation of the ATS-34 sanmai billets enabled the ATS-34 steel to appear in kitchen knife making. Notably introduced by RyuSen around 2015-2016.

Although this line has a mirror polish finish, the stickness found on typical mirror polished blade seems to be absent when cutting into a potato. It seems to us Yoshihiro Yauji put on a convex grind on the bevel, wich reduces the drag when the blade is contacting the food. Paring that with a rather thin grind, it glide effortlessly even when spliting a potato right through the middle.

One noteworthy freature about Yauji's knifes is that the Santoku he forges takes a rather unique profile, similar to a Sanjo Gyuto. These Santoku are thin and wide, offering them excellent stability when cutting vegetables. Their tips curves up significantly, resulting a round head compare with the flat belly of a typical Santoku. This geometry means that rocking motion is much easier to do on Yauji's Santoku, making them even better at handling vegetables of all kind, which is a perfect fit for Santoku's purpose.

This ATS34 line not only look good, but also cuts well, if you are fancying a shiny damascus knife, these blades can be a choice that pack some good performances.

Care Instruction

Don't cut hard things! Japanese knives are brittle so bone hacking is a NO NO!
Wash with neutral detergent after use, and wipe dry;
Please don't wash knife with dishwasher, it will damage the wood handle;
Be careful not to leave the knife close to a heat source for a long time;
It is a lot more dangerous to cut with a blunt knife than a sharp knife!
It is best to sharpen a Japanese knife regularly on a waterstone.

Yoshihiro Yauji

Yauji Yoshihiro(弥氏良寬), born in Echizen, Fukui Perfecture in 1983. At age of 20 in 2003, he entered Kitaoka Knives to apprentice under Kitaoka Hideo(北岡英雄), the third generation bladesmith of Kitaoka Knives. In 2019, he acquired the Traditional Craftsman Certification, which is quite remarkable, considering by average it take 25 years for a bladesmith to accomplish this goal.

In April of 2021, Yoshihiro Yauji left Kitaoka Knives and set up his own independent knife workshop Kutsurogi(寬), which shares a same Kanji with part of his name. Kutsurogi along with Yoshihiro Yauji is now a part of the Takefu Knife Village, which is an association that consists 14 knife companies and more than 40 bladesmiths, all located in Echizen area. With big names like Yu Kurosaki, Shiro Kamo and Yoshimi Kato, the Takefu Knife Village has a total of 17 Certified Traditional Craftsman, working and communicating with each others, they make the association a remarkable force in the industry.

Yoshihiro Yauji's knives are often found in damascus, with a color that is usually brighter than what you find on other makers. These blades seems to be grinded with a convex bevel, wich helps prevently food sticking greatly, especially when paired with a more"sticky" finish like a mirror polish. With this skillfull grinding and great fit and finish, Yoshihiro quickly gained fame and reputation as a relatively young bladesmith in Takefu Knife Village.

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: ATS34
The ATS-34 steel, manufacturerd by Hitachi Special Steel, is the Japanese equivalent of the 154CM, famous for its toughness, corrosion-resistance and "high-speed" properties.

The 154CM was originally designed for jet engine turbine use, however it found its fame in the knife world after legendary knife maker Bob Loveless started using them for his hunters. In the years after that, the 154CM / ATS34 was considered as the top of the line steel by many makers and is still considered so. The high-manganese alloys provides a favorable combination and balance of properties like ductility, formability, strain hardening, and strength.

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: Mirror Polish

Mirror Polish is a simplistic yet hightly demanding process, where the roughness of the metal surface is gradually removed with higher and higher grit abrasives, leading to a extremly smooth surface with only specular reflection, just like a mirror.
The Mirror Polish can be applied to various constructions, ranging from Damascus to Honyaki. It can reveal the beautiful Hamon on the Honyaki blade, and form textural contrast on damascus. The perfect surface is highly appreciated, but it also means a lot of care must be give to avoid it being scratched.
