Introducing our new Hokiyama Aogami Super Tosaichi knife set, crafted to delight Japanese blade enthusiasts who admire the blend of a classic western handle and just the right amount of added weight. Prepare to be impressed by the top-notch craftsmanship and unbeatable performance of these beauties. 

Hokiyama Gyuto Aogami Super Tosaichi 210mm (8.3") and Hokiyama Petty Aogami Super Tosaichi 135mm (5.3") knives are both suitable for professional users and home cooks who are familiar with handling and maintaining high-carbon knives. Get ready to elevate your cooking game to new heights!

Petty is a small general-purpose knife. An essential part of any knife collection, its main tasks are peeling, paring, decorating, coring apples, removing eyes in potatoes, chopping herbs, mincing garlic, slicing smaller pieces of dry meats, trimming meat, and similar tasks. Best suited for in-hand usage because the narrow blade doesn't allow enough knuckle clearance to use on the cutting board.

The gyuto blade shape is essentially a Japanese version of the Chef's knife, which will make this knife suitable for preparing large quantities of vegetables and meat. The 210mm length is optimal for everyday, versatile use, regardless if you are a home cook or a pro chef.

The centerpiece of the Tosa-Ichi knife series is Hitachi's Super Blue Steel (Aogami Super), which ranks at the very top of quality Japanese steels. Aogami Super steel is extremely rich in carbon content, which directly affects the blade's hardness. It also contains 0.4% vanadium which gives the steel more toughness.

Aogami Super is rated as the most advanced carbon steel on the market. High-carbon steels need more maintenance as they quickly develop a protective patina, and if not wiped and dried after every use, they will develop rust. But - Hokiyama made it a bit easier for us. The two outer layers of softer, SUS405 steel are rust-resistant, which offer more protection from rust, although the Aogami Super is still exposed at the very edge (the visible, curvy line on the bottom of the blade represents the line between core and outer steels).

This knife set was heat-treated to the hardness of around 63 HRC. It is extremely hard steel, meaning that it retains super fine sharpness for a long time despite its extensive usage. In addition, due to the high carbon content, the knife is very easy to sharpen.

The upper part of the blade is black and was left untreated. This scaly residue remains on the blade after the process of heat-treatment of the steel and is called kuro-uchi. Kuro-uchi patina brings a unique and rustic appearance to the knife. 

Both knives were fitted a western-style (Yo) ergonomic handle made of durable laminated pakka wood, secured to the tang with three stainless rivets. The also stainless nickel-silver bolster gives the knife a gentle transition from the handle to the blade and provides a comfortable and firm grip during use.

Hokiyama Hamono is a leading smithy in Kochi Prefecture in Japan. They have recently celebrated their 100-year anniversary, founded in 1919. Hokiyama Hamono is known for their quality as they follow the tradition of hand-made blades that has been around for over 800 years. They retain the handiwork and traditional craftsmanship that is passed down from generation to generation while striving for the ever-new knowledge and innovation. Despite the fact that they make knives according to the traditional methods, they follow the modern technological guidelines in the field of metallurgy, material processing and innovations in production processes. Hokiyama, in their own words, is a fusion of tradition (土佐 一), innovation (無限) and practicality (左近).

Each knife in the smithy goes through about 50 different processes that are performed and controlled by experienced craftsmen. Among the various steps required to make a Hokiyama knife is a special process called Rolling-Forging. It enables the efficient and uniform production of knives while maintaining the properties and qualities of Japanese steel.

☝️ Japanese kitchen knives in our store are handmade from natural materials. Slight variations in color, texture, weight and other dimensions are possible. We try to give a good photographic representation of our products, however computer screen resolution and colors do vary, so products might not look exactly as they are seen on screen.


Knives made of carbon steels can, due to their low chromium (Cr) content, discolor and develop patina. The knife is the most sensitive when it is still new and a patina had not developed yet, but later, patina will protect the blade. These types of knives require a touch more care:

✔ Wipe it regularly with a clean and dry cloth (you can also do this during use).
✔ After use, rinse it with lukewarm water and wipe it dry.
✔ Coat it regularly with knife maintenance oil or plain refined sunflower oil.
✔ Store the knife by wrapping it in paper which will absorb moisture and protect the blade.

A patina is a thin layer that forms on the surface of oxidized steel and protects it from further oxidation. The patina should not be confused with rust. Patina protects the blade, while rust causes corrosion and deterioration of material, so it should be removed (see Rust erasers).

→ For in-depth information about patina, read our dedicated post on patina.


Blade wear depends on the quality of steel, usage and maintenance of the blade. Japanese knives are made of high-quality steels. Follow these tips to keep your Japanese knife in top-notch shape:

✔ Use a wooden, plastic or rubber cutting board.
✔ After use, wash the knives and wipe them dry.
✔ For storage, use a knife holder or a protective knife sheath (saya).
✔ A good cutting technique is your best bet to prolong sharpness.
✔ Use sharpening stones to sharpen the knife.

❗️Don’t leave the knife in the sink. Wash it by hand.
❗️Don’t wash the knife in the dishwasher.
❗️Don’t use the knife on glass, ceramics, marble or steel surfaces.
❗️Don’t scrape the food off the cutting board with the edge of the blade. Use the spine of the knife instead.
❗️Knife is a tool intended for specific use - cutting food. It is not a can opener, screwdriver, trowel, wire cutter, hammer etc.
