The Yoshikane KU Nashiji line puts a carbon steel core inside stainless cladding that is easy to look after.

At its core is Hitachi White #2, a pure carbon steel that takes a keener, more refined edge than harder steels with more chromium. Yoshikane's thin, convex grind and significant blade taper let the knife slice with minimal resistance and virtually no wedging, even in dense potatoes.

The finish leaves the nashiji (pear skin) texture darker and more subdued under a rugged kurouchi (KU) coating, a matte, utilitarian look.

You still get close fit and finish: a highly polished spine and choil for comfort, and a clear contrast between the rough finish and the polished edge.

For pure cutting performance, the line offers real value.

Pros Cons
  • Excellent performance
  • Great for professionals
  • Thin behind the edge
  • High budget
  • Prone to rust
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.

Yoshikane Hamono

Traditional Sanjo Knife Maker.

Yoshikane is a knife maker in Sanjo, Niigata, founded in 1919 by the first generation, Kanekichi Yoshida, in the district of Shimotajima. More than a century later the company still works from Sanjo, and it has been incorporated as Yoshikane Hamono K.K. since 2022. Kazuomi Yamamoto (山本和臣) has held the name as the fourth generation since 2013.

In his greeting, Yamamoto writes that Sanjo is known nationwide as a hardware town, a standing that comes from the history of the smiths who made blades and carpentry tools and the hardware wholesalers who traded them, carrying the work from one region across the country. He says Yoshikane has carried on the old Sanjo smithing line through its century of work, making knives one by one by traditional methods, and its site says its craftsmen make each knife by hand. Yamamoto works under the motto Fueki Ryuko (不易流行), which he explains in his own way: amid the way things change at speed, some things stay firmly the same. He writes that in the knife making he puts his care into, he tests the deep meaning of those words every day.

The company's own history marks 1919 as the year it began making Japanese knives under a brand of its own and as OEM work for Sanjo hardware wholesalers; 1922, when the second generation took the name and the company added two further house brands; 1948, when the third generation began making double bevel knives; and 2002, when it moved to the Kaneko Shinden industrial estate and showed at Ambiente in Germany under the Yoshikane name, which began its export in earnest.

The Yoshikane knives we list are the Hatsukokoro x Yoshikane SKD Nashiji line in gyuto, K-tip gyuto, santoku, bunka, petty and sujihiki, along with a White 2 Nashiji sujihiki, and the Yoshikane White 2 Nashiji knives, some stainless clad and some under the Hatsukokoro name, in bunka, nakiri, petty and sujihiki.

“A Sanjo knife maker since 1919, now in its fourth generation.”

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.

Shirogami 1 vs shirogami 2 — what is the difference?

Shirogami 1 (White 1) has a higher carbon content than Shirogami 2 (White 2), roughly 1.3% vs 1.1%.

White 2 (Shirogami #2) has about 1.1% carbon and, per Proterial, a hardening hardness of over 60 HRC; White 1 sits around 1.3% carbon. That 0.2% difference is the core spec gap. More carbon generally means you can push hardness higher and hold a keener edge, but it also makes the steel more brittle and less forgiving. White 2 trades a bit of that potential peak sharpness for slightly better toughness and ease of sharpening.

Shirogami 1 carries a certain prestige. Sukenari's Nobuo Hanaki once told me directly that they only use White 1 for their mizu-honyaki because it is the pure form of carbon steel, it carries that halo. Among traditional smiths, White 1 is still spoken of as the benchmark.

How old is Yoshikane?

Yoshikane's own company page dates the founding to Taisho 8, 1919, when Kanekichi Yoshida started the business in Shimotajima, Sanjo.

The same page records the fourth generation, Kazuomi Yamamoto, taking the name in 2013, and the company's incorporation as 株式会社吉金刃物 in 2022.

Is Yoshikane written 吉金 or 吉兼?

Both forms are correct, for two different things: the company writes its own name 吉金刃物, as the maker's site shows.

That page also records 吉兼 and 吉兼久 as the workshop's own brands, added in 1922.
