Every few years Sukenari works a steel nobody else has bothered with. ZDP-189, HAP40, SRS-13, YXR7, and now ZDP-247. It is not a new alloy. It comes from the same Hitachi (now Proterial) ZDP family as ZDP-189. Murray Carter was working a ZDP-247 variant back in the early 2000s, and described it as a steel made for forging rather than grinding from a blank. The steel came out of Hitachi about thirty years ago, and Sanyo Riki, the mill that laminates Sukenari's billets, says roughly a ton of it is left. What is new is a production kitchen series, which Sukenari debuted in August 2026. As far as we can tell, we are one of the first shops anywhere to sell commercially available ZDP-247 kitchen knives from a reputable maker, and possibly the first.

Now the honest part. Sanyo Riki calls ZDP-247 a development grade, and the only thing we have been told about it is one line: powder stainless, heat-treat it like SRS-13. Proterial has never published a specification at all. So we cannot give you a carbon or chromium figure, because nobody outside Proterial has one.

What we can give you is how it cuts. Sukenari takes it to 63 to 64 HRC, a touch under where they run ZDP-189. It is a hard powder steel and it holds an edge like one: a long plateau, then a clear signal that it wants the stones. The surprise came on the stones themselves. We put the 247 and the 189 on the same ones, and the 247 gives up a burr without the fight. It still rewards a good stone. It is stainless on paper. So is ZDP-189, and that still spots if you leave it wet. Wipe it, keep it dry, and do not twist it through bone.

This is the Hairline: a stainless-clad san-mai with the ZDP-247 core between softer stainless layers, brushed rather than mirrored. Same construction and finish as the ZDP-189 Hairline that so many of you own, so the feel in hand and the thin grind behind the edge will be familiar. If you own the 189 and want the next chapter, this is it. If you are new to steels this hard, start with the ZDP-189 Hairline and come back for this one.

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.

Sukenari, professional kitchen knives from Toyama

Sukenari Co. makes, sells and repairs professional kitchen knives in Fuchu-machi, Toyama City, under the registered mark 佑成. The company was founded in 1933.

The company's own greeting page explains the mark: its first character is written with the person radical and 右, meaning right, and carries the wish that these knives can become the cook's indispensable right arm.

A 2016 profile by TONIO, Toyama's industry support body, says the founder trained at an old-established Tokyo knife maker and opened the shop in his home region in November 1945, after a wartime evacuation there. Knife regions split forging, sharpening and handle fitting between specialists; that profile says Sukenari makes its knives start to finish under one roof, as that Tokyo house did. Its own site says craftsmen still make every stage by hand, one knife at a time.

The same profile credits Sukenari with honyaki in White 1, a very hard steel that is hard to work and that, it says, only a handful of makers in Japan can handle. It also describes know-how built for ZDP189, harder than White 1, and TONIO-backed forging trials, with metallurgy and measured heat treatment, that led to its ZDP189 wa-gyuto. The profile also tells of OEM work for other professional knife makers and wholesalers since the 2008 downturn. We first visited in April 2016, when Nobuo Hanaki, then president, showed us the forging.

We list ZDP-189 hairline gyuto, K-tip gyuto and santoku; ZDP-247 hairline or Damascus gyuto, K-tip gyuto, santoku and sujihiki; SG2 hairline or Damascus gyuto, K-tip gyuto, gyu-hiki and santoku; HAP40 slim K-tip gyuto and mirror polished yanagiba; VG XEOS Damascus gyuto; VG10 Damascus yanagiba; YXR7 petty; Aogami Super hairline gyu-hiki; Blue 2 deba, K-tip yanagiba and Kanto usuba; White 2 K-tip kiritsuke and K-tip yanagiba. We also list an SG2 honyaki yanagiba, including a K-tip, an SG2 nimai (two-layer) sakimaru takobiki, and VG XEOS nimai yanagiba and kiritsuke yanagiba.

“A Toyama maker of professional kitchen knives since 1933.”

Frequently asked questions

Is a K-tip Gyuto the same as a traditional Kiritsuke?

Not quite - and it is the single most common point of confusion when people shop for a kiritsuke. The two knives share the same striking angled, reverse-tanto tip, but underneath that tip they are very different tools.

A K-tip gyuto is normally a double-bevel knife: it is ground on both sides like any Western-style chef's knife, so it is forgiving to use, and sharpened exactly the way you would sharpen a normal gyuto. You get the dramatic kiritsuke look with the everyday usability of an all-purpose chef's knife.

A traditional kiritsuke, including the kiritsuke-yanagiba (slicer), is a single-bevel knife, ground on one side only. It is historically a master chef's knife: it takes real practice to use well, is set up for right-handed users by default, and needs single-bevel sharpening technique to maintain.

So if you want the kiritsuke silhouette with no learning curve, choose a K-tip gyuto. If you specifically want the traditional single-bevel discipline - and the precision it allows on fish and vegetables - choose a true kiritsuke. At Knives and Stones we stock both, and each product page tells you which construction you are looking at.

Is it Sukenari or 佑成?

Sukenari's own site carries both names together, titled the official site of 株式会社スケナリ with 佑成 named as a registered trademark. 佑成 is the house mark that appears on the blades.

So one house answers to both names: Sukenari is the company, 株式会社スケナリ, working from Fuchu machi in Toyama City, and 佑成 is its mark on the steel.

Are Sukenari knives handmade?

Yes. Sukenari says its knives are made by craftsmen by hand, one at a time, at its workshop in Fuchu machi, Toyama City.

The Sukenari lines we stock carry the workshop name in their titles.

What does the Sukenari mark 佑成 mean?

The workshop says the 佑 of its registered mark 佑成 (read Sukenari) is written with the person radical and 右, right, and that the character carries the wish for its tools to become the cook's indispensable right arm.

The company's own site title reads 登録商標佑成 (registered trademark), and 佑成 is the house mark on its blades.
