Hado/Ouru SLD line is a lineup with a bit complex background, made with an excellent material that has great edge retention, maintainability and aggressive edge, this forged lineup has a heavy duty blade that is sharpened pretty thin. It is a beauty and a beast, a beloved weapon for those who like to weld tip heavy knives, and its identity took me some digging to find out.

The SLD steel strictly speaking is not a stainless steel, although having a pretty high chromium level, the high carbon content results in a lot of chromium carbides, leading to less chromium participating in rust resistance. But, unlike other semi-stainless such as SKD, SLD will barely pick up a patina, so if dried properly, it can be very easy to take care of, and its edge when dulls, will retain some of the aggressive feeling like a carbon steel edge does.

To talk about the build, I think it’s important to figure out its creator. Although labelled with “Hado Ouru”, I believe this is not a knife produced in Sakai. Ouru or Oul are just the different spelling of the same brand “翁流”, And Oul Sakai is the older name of the knife brand under Fukui Co. before they opened their in-house sharpening workshop in 2019 and launched the Hado brand in 2021. The knife is sharpened with a rather low Shinogi line, instead of the typical super wide bevel design Hado uses, its forging keeps the strong taper in the spine and a lot of thickness in the blade, and overall the style is full of Sanjo features. I found some Ouru knives with a similar SLD finish featuring a very familiar handle, identical with the Hocho Kobo series from Tadafusa, then it all started to make sense. Judging by the features of these knives, I can almost certain these are knives commissioned by Ouru to Tadafusa, these products are kept and carried over after the founding of Hado, and they are sold under the Hado/Ouru name with Ouru engraving to differentiate from the sharpened-in-house Hado knives.

Tadafusa’s approach on sharpening is quite different from Hado, they kept the bevel rather thick and paired it with a convex grind, this is a design that emphasises food release, and indeed we found potato slices barely get caught on the blade. Although the thickness of the knife does cause some difficulties when dealing with dense and tough roots, the low thickness behind the edge still allows the knife to enter most of the food with little resistance, and the weight of the knife will carry the cut through the food with great smoothness.

This is a very Sanjo knife under a Sakai brand, and I quite recommend it for users who like that reassuring weight from a heavy knife. The hand forging, rustic Nashiji finish and smooth hand sharpening lead to a very characterful lineup. It is a great line to work with for professionals or knife enthusiasts with its great cutting characteristics.

Pros Cons
  • Workhorse grind
  • Exceptional profile
  • High budget
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. Semi-stainless steel won't rust easily but may still patina

HADO

HADO (刃道), Fukui Co.'s Sakai knife brand

HADO(刃道), a brand launched in 2021 under the banner of Fukui Co., Ltd. Its name translates directly to “The Path of Blade” and its founding has an interesting story to it. Being a company located in Sakai, its products are straight up a defiance to Sakai’s impression of old-school, traditional approach in knifemaking, and this young brand has shown us what Sakai is capable of in terms of innovation and breaking existing rules.

In 2015, Tadataka Maruyama, sales representative of Fukui Co. decided to quit his current position and pursue the craft of knife sharpening, particularly Hatsuke(刃付け)-the process of giving the knife its bevel geometry and edge. The then president Ryuichiro Fukui told him to properly train himself and return to the company after three years, and in 2021, under the support of Fukui Co., Hado was founded.

Typical Sakai approach in knifemaking would begin with a forged blade with intermediate thickness, sharpening in a lightly convex geometry where the bevel transitions smoothly to the Hira. After the finishing polish using a wooden wheel or sandblaster, the Kasumi finish would look like a uniform surface from the side. Hado took a very different approach in their knife design, staring with a slightly thinner blade that measure just above 2mm in the spine, they put a very aggressive bevel onto the blank, the Shinogi line is clear and defines, located close to the spine, which means a lot of material are removed and the bevel stays thin until very high up. This means minimal wedging in cutting even if you are dealing with a tough produce, and the sticking issue is solved via a subtle convex grind behind the edge.

The material choice is when you sense the tradition they the brand is clinging to, using mostly Blue, White and Ginsan, these blades forged with traditional materials are polished differently to create variety. What is consistent is their incredible sharpness and top notch fit and finish, with mirror polished spine and choil blends seamlessly into the organic Nashiji/Kurouchi blade and Kasumi finished bevel. Meanwhile, Hado is very open to newer material and manufacturing techniques too, the newly released Shiosai features a stamped SG2 billet and they can offer great value with the same Hado sharpening.

In July 2025, the sharpener Maruyama announced his independence from the company, and started his own store in Nara, his colleagues took over the sharpening task and held up the quality to the standard after the change. In the city of Sakai where tradition reigns supreme, we can still see innovation from a young brand. Initiating its journey backed up by the trust and faith of Fukui Co., Hado’s efforts have been proven effective by their popularity amongst knife lovers, their success have pointed out a path of innovation for the industry, and we will be happy to see more vitality getting brought into this market.

“The knife brand launched by Fukui Co. of Sakai in 2021.”

Knife details

Frequently asked questions

Why is it called a bunka knife?

The bunka knife (文化包丁) takes its name from bunka, culture. A Sakai knife maker ties the name to Japan's modernisation, when Western culture and Japanese tradition merged, and says it stands for that new era and for the knife's wide range of uses.

The same maker says that as diets broadened to meat, fish and vegetables, an all-purpose knife was wanted, and the bunka took features from both Japanese and Western knives.

What is the difference between a bunka and a santoku?

The tip. One Japanese knife maker describes the bunka (文化包丁, kengata) as combining the good points of the gyuto and the nakiri with the tip cut at an angle, and the santoku as coming after it, by rounding that tip.

Both are all-purpose knives for the home; santoku (三徳) means three virtues, for the three foods it cuts: meat, fish and vegetables.

Is SLD the same steel as SKD11 and D2?

Close. Proterial, which makes SLD, lists AISI D2, DIN X153CrMoV12 and JIS SKD11 as its equivalent standards, while its own typical figures include 12% chromium and 1.5% carbon.

Proterial makes SLD as a cold work die steel with high abrasion resistance, for uses such as cold press dies, shear blades and gauges.

Is Hado a blacksmith or a brand?

Hado is a brand: its own site calls it a Sakai knife brand.

The company named on that site is Fukui Co.
