Sakai Takayuki is a Japanese kitchen knife brand of Aoki Hamono Seisakusho, a cutlery maker based in Sakai, Osaka. Drawing on the techniques of Sakai forged cutlery — a government-designated Traditional Craft of Japan — its range spans traditional professional Japanese knives through to stainless models that are easy to use at home. Sakai Takayuki knives are used by cooks around the world.
On this page, Hayashi Hardware — a Japanese cutlery shop founded in 1872 — explains the background of the Sakai Takayuki brand and how to choose between the series we carry.
The Sakai Takayuki brand
Aoki Hamono Seisakusho is headquartered in Sakai, Osaka, often called the home of Japanese cutlery. Sakai is said to produce the great majority of the traditional knives used by Japanese professional chefs, and it is known for a division-of-labor system roughly 600 years old in which forging, sharpening and handle-fitting are each done by specialist artisans.
Sakai Takayuki knives are built on that tradition. The brand's series range from traditional honyaki and kasumi knives to Damascus and practical stainless models, chosen both as tools by professional cooks and as gifts.
The Sakai Takayuki range — from Japanese knives to confectionery and soba knives
The Sakai Takayuki range is extremely broad. The maker's official website groups it by use as follows (series names are a selection from the official listings).
| Category | Main series and products |
|---|---|
| Japanese knives (wa-bocho) | Honyaki, Kasumi, Aogami #2, Ginsan clad, Damascus, INOX, and named series such as Homura, Shiden, Hien and Genbu |
| Western-style knives | Grand Chef, INOX Wa, TUS, 33-layer Damascus and more |
| Chinese cleavers | Various Chinese cleavers, INOX |
| Confectionery, soba and specialty | Castella knives, soba-cutting knives, tofu knives, tuna knives and more |
| Whetstones and tools | Coarse, medium and finishing whetstones, knife cases and more |
Most of the range is specialist knives for professional cooks, but there are also double-bevel stainless models that are easy to use at home. Note that the INOX Wa series we carry is listed as a Western-style knife on the official website: it combines Western shapes — gyuto, santoku and petty — with the same octagonal handle used on Japanese knives.
The Sakai Takayuki series we carry
Hayashi Hardware carries two stainless series that are easy to care for at home.
| Series | Steel | Features | Best for |
|---|---|---|---|
| Kurokage | VG-10 (HRC 60–62) |
Black blade with hand-hammered texture and fluorine coating. Excellent food release and long edge life | Cooks who care about both sharpness and looks |
| INOX Wa | AUS-8 (HRC 58–59) |
Bright polished silver blade. Crisp cutting, easy to sharpen, worry-free for daily use | A first Japanese knife; practicality first |
Both come in three shapes — Gyuto 210mm, Santoku 170mm and Petty 150mm — with octagonal handles in Ho wood, Wenge or Ebony (with a water-buffalo horn ferrule). All have a double-bevel edge, so they suit right- and left-handed users alike.
A closer look at Kurokage
How the hammered finish and black coating work
The Kurokage blade is VG-10 steel given a hand-hammered texture (tsuchime) by a craftsman, then finished with a black fluorine coating. The hollows of the hammered finish create pockets of air between blade and food, and together with the slick coating they help sticky foods such as potatoes and raw meat fall away from the blade.
Why does the black come off the edge when you sharpen it?
Sharpening on a whetstone grinds away the coating at the very edge, revealing a thin line of silver steel underneath. This is not a defect — it shows the edge has been freshly sharpened. The black on the sides of the blade and in the hammered texture stays for a long time because the stone does not touch it. Cutting performance depends on the steel at the edge, so losing the black there does not affect sharpness.
Santoku, gyuto or petty?
- Santoku 170mm: an all-rounder for vegetables, meat and fish. The best first knife for most home kitchens
- Gyuto 210mm: the longer blade makes slicing large cuts of meat or shredding cabbage easier. For larger households and keen cooks
- Petty 150mm: for fruit, garnishes and small prep work. A good second knife alongside your main one
Handles come in Ho wood, Wenge or Ebony. The blade is the same whichever handle you choose; only the handle material, weight, look and price differ.
Kurokage or INOX Wa — which should you choose?
- For lasting sharpness and presence, choose Kurokage — VG-10's hardness means less frequent sharpening, and the black blade takes center stage in your kitchen. Read our VG-10 guide
- For ease and value, choose INOX Wa — AUS-8 is easy to sharpen and more affordable, ideal as a hard-working first knife.

What is Sakai Takayuki's reputation? Three common questions
Aren't they just mass-produced knives?
Aoki Hamono Seisakusho runs its own factory in Sakai, and its forging and rough-grinding work is shown to visitors on factory tours offered through the Sakai Tourism and Convention Association. These are knives made by craftsmen in Sakai, home of Sakai forged cutlery.
Is it the same wherever you buy?
The same series and model is the same knife. What differs is who you can turn to afterwards for resharpening and advice.
Are they too professional for home use?
Some series — honyaki or single-bevel Japanese knives, for example — are aimed at professionals and take practice to maintain. The Kurokage and INOX Wa knives we carry, however, are double-bevel and stainless, so they resist rust and suit cooks using their first Japanese knife at home.

Frequently asked questions

Sakai Takayuki is a kitchen knife brand of Aoki Hamono Seisakusho in Sakai, Osaka. The knives are made in Sakai, home of Sakai forged cutlery, a Traditional Craft of Japan.
Q. What is the Kurokage series?
Kurokage ("black shadow") is a line of knives with a VG-10 steel blade, a hand-hammered tsuchime texture and a black fluorine coating. Hardened to HRC 60–62, it holds its edge for a long time, and the hammered finish and coating reduce food sticking to the blade.
Q. Do Sakai Takayuki knives rust?
The Kurokage (VG-10) and INOX Wa (AUS-8) knives we carry are both stainless steel and highly rust-resistant. Wash and dry after use and rust is practically never a concern. They are not dishwasher safe.
Q. Can Sakai Takayuki knives be resharpened?
Yes. They can be sharpened on standard whetstones, and we also offer a mail-in sharpening service. The black coating on Kurokage wears gradually at the sharpened edge, which does not affect cutting performance.
Q. Are they suitable for left-handed users?
Yes. Both Kurokage and INOX Wa knives have a double-bevel (symmetrical) edge, so they work equally well for right- and left-handed cooks.
Q. Are the Kurokage blades different between the Ho wood, Wenge and Ebony handles?
No, the blade is the same. Only the handle material differs, which changes the weight, feel, look and price.

It is on the ground floor at 2-2-22 Kurumanocho-nishi, Sakai-ku, Sakai, Osaka — a gallery and lounge run by Aoki Hamono Seisakusho. Opening days and fees may change, so please check the maker's official website.
