Hokiyama Usuba AUS-8 180mm (7.1")
Best To Use
(click on icons for more knives)
Hokiyama Usuba AUS-8 in 180mm (7.1") blade length is a dedicated knife for vegetables only. It's a single bevel knife, which means only right-handed users can wield it.
This rectangular-shaped usuba (named Kakugata in Japanese) was polished to a high (almost mirror-looking) polish. The minimalistic blade is fitted with a traditional Japanese (Wa) handle made of of dense, durable wenge wood with a darker plastic ferrule. There is a slight step between the ferrule and the handle, which might bother some users.
Where the blade meets the handle, you may notice a special feature called Machi spacing. This is a small gap between the lower part of the blade and the handle, which can be seen mostly in Yanagiba knives. It is a feature that pays tribute to Japanese swords and is typical mostly in the work of blacksmiths located in and around the Tokyo area. So don't worry, it is not a flaw in assembly of the blade and the handle, but rather a homage to Japanese forging tradition that could be displayed on a magnet right there on your kitchen wall.
The blade consists of 2 layers of steel - the harder steel AUS-8 (60 HRC) and a layer of softer stainless steel are forge welded together in what is known as "nimai" construction. AUS-8 steel is a popular Japanese steel from the Aichi steelworks that is incredibly resistant to rust, yet simple to sharpen. The steel contains high amounts of carbon (0.7-0.75%) and is also high in vanadium (0.10-0.26%) and molybdenum (0.10-0.30%). It also has a high percentage of chromium (14.5%), making the blade corrosion-resistant and increasing the hardness, durability and the tensile strength of steel mix.
This carefully balanced composition does not only endow the blade with exceptional hardness (60 HRC) but also good wear and tear and rust-resistance properties.
→ Long lasting sharpness: 60 HRC hardness and high carbon content make the blade razor-sharp and help it retain its edge for a very long time.
→ Rust-resistance: due to high chrome content (14%), the steel is very resistant to corrosion. Even so, you should not skip any of the steps of blade maintenance: wiping it with a dry cloth after use and storing it correctly in a dry and safe place are important steps for prolonging the service life of your knives.
→ Wear and tear resistance: the composition of this steel mix also makes the blade very resistant to wear and tear.
Due to the choice of materials and precise final treatment of the blade by hand, the blade is simple to maintain, retains its edge for a very long time and is perfect for sharpening on water stones. These are essential characteristics of a traditional Japanese single bevel knife, such as Usuba.
Suitable for first-time buyers of a Japanese kitchen knife. It can also serve as a wonderful gift!
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.

Yesterday I cooked a Chinese meal for a couple of friends: a main mie dish and verious side dishes. Preparing all the vegetables and meat with this Santoku was a joy: effiortless and precise cutting. Probably this inspired me to be as precise in the cooking itself, because we all agreed that it was the best version of this recipe I ever made.
This is the second knife I purchased from SharpEdges. The first one - a Yoshida kiritsuke 135 mm black HAP-40 is also very good. I like the (almost) minimalistic simple but (almost) perfect finish of these Yoshida blades and handle.
All in all I regret that I did not discover your shop earlier. I already have a nice collection of other Japanese knives with different steels and shapes. No need on the short term for replacements or filling some gap. But who knows?
Delivery by DHL Express from Ljubljana to the Netherlands is okay but not perfect. Oh well. Who cares?
Thanks guys for the good service, the European sense of humour and the - especially that - great products.
Well received and everything in great condition, great knife bag and the blade covers fits perfectly... Thanks
Ciao, ho acquistato questo coltello per tagliare la pasta che faccio in casa. Premetto che sono mancino per cui gran parte dei coltelli giapponesi faccio fatica a trovarli. Il coltello è piacevole ma non propriamente da mancini. Un saluto
Very special handle,nice!
I just received my Yoshida Hamono ZDP189 santoku and I am over the moon with it. It was a hefty purchase, but well worth it. I’m currently restoring my knife collection since my previous one was stolen. This is a wonderful addition to my new collection.
Nice wrapped and really safe, amazing knife as a Santoku I had bought and really comfortable to use for whole day prep in the professional kitchen.
I purchased a knife from this website, unfortunately the knife was not of my liking, they provided a return label for me, then Fedex lost the package and it was a mess, lots of calls and emails but sharpedgeshop was always professional and gave me a full refund, they always responded to my emails quick and were very professional.
During the Purchasing process and a year later when I wanted to have something repaired, the service has been outstanding. Prompt responses and working with me to find the right solution.
Beautiful blade and handle. Thanks Sharp Edge!
Will be buying from here again due to the fact that the customer service made me feel like no matter what I'd have everything I needed and be getting my money's worth. They care about your experience and also have brilliant products
Knife was bought as a gift and the receiver loves it. They were responsive when emailed a question and the knife arrived fairly quickly.
It was a pleasure to shop here, so much information and good advice to help you find what you are looking for, pair that with exceptional service and communication and you have a shop who is dedicated and passionate about what they do. Highly rated and thank you
I ordered a knife for a friend with custom engraving and the customer support went above and beyond to help make sure I received the product I asked for. They were quick, friendly, and considerate, and shipped the knife extremely quickly. When a part of the Saya was damaged during delivery I received a replacement (several just in case) the next day!
The knife itself looks great, is nice and sharp, and is exactly what I had hoped to order. Will definitely order again for myself.
I'm really satisfied with the quality of the knife. A great product. And the customer service was great. I have a very small thing to share and it’s not a complaint at all. The knife was a gift and overall the packing is okay. But the knife box was a little bit low quality and i hope that would be okay with lots of customers and if there is an option to buy a little bit higher quality box, it would be very nice. Thank you.
Prompt and reliable team at “Sharp Edge”. I received my item promptly and was well packaged. I had a query about the handle before I purchased this knife. The team at Sharp Edge actually went to the trouble of doing a test and gave me an answer in four days.(I asked them about the suitability of composite handles for sanitising in hot water). All Is good!
