ZDP-189 Bunka Black is our bestseller. How come? In short, it is our very own design, a result of years of our experience with Japanese knives. We wanted to create a knife that connects fine Japanese craftsmen skills with the needs of the Western-type cuisine. Meet Bunka.
Bunka was designed in harmony with our values (excellence, quality, and reliability), in line with those originating from the steadfast Japanese tradition. We also devoted special attention to certain aesthetics inspired by Japanese mysticism and a respectful attitude to tradition, nature, raw materials, the constituent elements, and the final product – in short, the quintessential values of Japanese culture.
With its typical functionality, Bunka design is intended for versatile use in Western cuisine. It has a flexible profile that is wide enough at the handle, a gently designed belly of the blade suitable for making either long or short cuts, a flat back side of the blade, and a thin tip for precise work with food.
The knife is manufactured at the smithy of Yoshida Hamono in Japan, a family company with an age-long tradition in manufacturing state-of-the-art tools and Japanese swords (katanas) by hand. Yoshida Hamono has a great deal of experience forging ZDP-189 steel in the traditional manner. See the photo story from our visit to their smithy.
The heart of the knife is made of ZDP-189 steel, which we selected because systematic testing has proven its superior qualities and long-lasting sharpness.
The steel is laminated, meaning that the core is made of very strong steel covered with an external layer of softer stainless steel - also known as san-mai clad. The softer external layer protects the core steel from external factors.
Kuro-uchi finish, the unprocessed (black) part on the top side of the blade has already developed a dark patina, which protects the blade and gives it a traditional Japanese look. The knife bears visible impressions of the hand-forging process (round hammer dents on the blade), which gives it a beautiful finish and also prevents food from sticking to the blade.
Bunka Black was fitted a traditional Japanese wooden handle, called Wa handle. The wooden handle is made of walnut wood with an octagonal shape, so it will fit equally well into the hands of right- or left-handed users.
The steel contains as much as 3% Carbon (C), which is one of the main elements contributing strength and typically found in amounts of up to only 1% in other types of solid steel, while the Chromium (Cr) content, which prevents corrosion, amounts to nearly 20%. It also features 1.5% Tungsten (W), which considerably increases the abrasion resistance of steel, 1.3% Molybdenum (Mo), which helps to preserve the strength and power of steel under variable temperatures, and 0.10% Vanadium (V), the key element in increasing steel strength. Heat treatment produces steel with a hardness of 65-67 HRC.
It embodies the cream of the crop as regards what one desires in a kitchen knife: the best steel, a multi-purpose profile, excellent functionality, and an attractive look. This makes it an ideal choice for anyone looking for a selection of the best properties for versatile use. Its superior qualities will excel in a professional environment with a large volume of cutting work, as well as for daily usage in your home kitchen.
The wooden knife sheath Bunka Saya, made of beech wood, was custom-made for the Bunka. Saya protects the knife when we are not using it. Saya is sold separately. You can select the option with the Saya when adding the knife to your cart.

Still doubting which type of Japanese knife should best fit your needs? We created a quick, 5-steps quiz to help you find the perfect knife based on your cooking skills and the type of food you prepare.
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!
