Fu-Rin-Ka-Zan White Steel No.1 Series FRKZW1-7 Bunka 180mm (7 inch)

Availability: Normally ships the same day

 Some of our loyal, longtime customers may remember the first knife models produced for our "Fu-Rin-Ka-Zan" (風林火山) Brand, which were hammer forged and handmade by the Forge Smith Teruyasu Fujiwara in the year 2012. Since then, we have concentrated on expanding the selection of Japanese "Wa" style Traditional forged knives (和風打刃物) that are available in our Fu-Rin-Ka-Zan range. Today, we are glad to be reviving the Fu-Rin-Ka-Zan White Steel No.1 Knife Series with the introduction of some new models.

 To produce these 風林火山 White Steel No.1 Series 'revival knives', we have once again worked with Master Blacksmith Teruyasu Fujiwara, who is a Licensed Sword Smith based in Tokyo. For over 4 generations, the Fujiwara family has maintained their traditional blade smithing techniques and processes, such as the Hidukuri (火造り) hot forging technique. 4th generation smith, Teruyasu Fujiwara, has a strong passion for traditional knives and produces them with great confidence. His desire is to make heirloom-quality knives that can be passed down for generations, allowing many people to experience and enjoy their exceptional cutting performance and the soul of traditional Japanese craftsmanship.

 The blade’s core is made from a very pure Japanese Carbon steel called “White Steel No.1" (SHIROGAMI #1) and is hardened to HRc. 63. This core has been forge-welded (Tan-setsu) with outer layers of soft stainless steel that have a unique surface texture, called "NASHIJI" in Japanese ("Pear skin"). We have found there is a fairly big demand for Carbon steel blades, especially from professionals and serious users; Many of these customers prefer very pure "White Steel" blades over other carbon steels because it offers remarkable cutting performance and is easy to re-sharpen. Unlike the stamped, die-cut or laser-cut blades of machine-made production knives, these hand forged blades are shaped with a hot forging process called “Hidukuri. This technique utilizes repeated hammer blows to improve the micro-structure of the Hagane ("Edge steel"), by making it finer and tougher. This secret is why forged knives have better edge durability and sharpness than production knives. For ease of maintenance, the outer layers of soft Stainless Steel provide good rust resistance (Only the blade core is likely to discolor or rust) and also increased resistance to bending and breaking.

 The light-weight handle is made from water-resistant Black Pakka Wood and the blade Tang is Taper Ground. The handle is slimmer than most Western-style handles that have a metal bolster, but it still provides a fine grip and is well balanced.

 These knives clearly show Master Fujiwara’s long history and experience with traditional forging techniques and processes, yet we think they will also meet the needs and demands of contemporary users. We especially recommend these fine traditional forged knives to people who appreciate or need extra cutting performance and people who would like to own a knife that displays the soul of craftsmanship.

 Each knife is fully sharpened with whetstones by hand, now available and ready to perform your cutting tasks.

 The Bunka is a general-purpose kitchen knife that used to be just as popular as the Santoku, but has become less commonplace in recent years. With its tall blade, the Bunka knife is particularly suitable for cutting vegetables or fruit and the triangular tip area is particularly useful for detailed work and cutting fish or meat.

Notice: Due to the hand forging process, the thickness of each blade will vary slightly. Compared with other knives, the portion of spine near the handle is relatively thick, but it consistently tapers towards the tip and provides great cutting performance.

Please Note: In general, Japanese Kitchen Knives are designed for right hand use and their blades have a relatively strong convex grind on the right-hand side and relatively weak convex grind (almost straight) on the left-hand side. However, double bevel edge knives with a 50/50 grind can be used by both right-handed and left-handed people without any problems.

We believe that Japanese knives have the best quality and cutting performance in the world, and we hope that you will enjoy the fine craftsmanship and sharp edge of your new knife. With proper care, your new Japanese knife will be your faithful cooking partner for many years to come.


The Carbon Steel blade core of this kitchen knife can discolor or rust easily. Consequently, extra care and attention are required to prevent it from rusting.

  • Please do not put the knife in a dishwashing machine for cleaning.
  • Please do not leave the knife in water or wet conditions for a long time.
  • After use, please hand wash the blade, bolster and handle thoroughly. After washing, wipe the knife clean and dry with a soft cloth, then apply Tsubaki (Camellia) oil to the blade before storing it in a dry place.
  • This knife is extremely sharp! Please use extreme care when handling and storing it.
  • Unlike German-made knives, Japanese knife blades are ground to a thin cutting edge for improved cutting performance and easier re-sharpening. Please protect the blade edge from hitting hard materials, or it might chip or crack.
  • Please do not use the knife to cut frozen foods, bone, or any hard shell foods such as lobster or crab.
  • When your knife eventually becomes dull, we recommend using Japanese whetstones to re-sharpen it.

    More than a year later

    I've used and sharpened this knife for over a year now. I felt compelled to add another review comment. This knife is awesome! It sharpens easily, has very respectiful edge retention and achieves an incredibly sharp edge. The tip is great for delicate cuts while the flat belly makes clean slices. I've added two more FKRZ knives to my stable and they absolutely rock! I've also added a Teruyasu Fujiwara Maboroshi gyuto to my kitchen and I have to admit - the Maboroshi line is emotionally more appealing, but in practice Fujiwara-san takes this steel close to his in-house hammer forged san-mai Maboroshi knives.

    Absolutely Amazing

    This beautiful piece of art has outstanding quality. Great looks, great feeling, and a combination of blade, size, and shape that make it a versatile powerhouse to easily chop through most things, no matter how soft or rough, no matter how fine or coarse. An absolute joy to cook with this amazing beauty.

    Good and bad

    First the good. The steel is amazingly sharp. I couldn't image a knife being sharper. There us tremendous satisfaction cutting with this knife. The knife has a very appealing "raw" astethics, at least to me. Now the bad. Amazingly sharp white steel no 1 comes with trade offs. The steel is super hard and has a "brittle" feeling to me. I have other carbon steel knives which are my preference and have dropped one before breaking off the tip. Although there is no evidence, when I use this knife it feels susceptible to chipping and I wouldnt comtemplate what would happen if dropped. Also disappointed in the tang and fitting of the scales. The top of the tang tapers from 6mm down to 2mm while the bottom of the tang is consistent 2mm. This variation cause the top of the scales not to be flush on the tang where a feeler gauge can pass between the scale and tang. In my view this is poor quality control. All together it's a great knife but the quality issue sets it back, certainly at this price point it's unacceptable. I've kept the knife in spite of its handle/ tang flaw but this might be a deal killer for many.

    A very unique series

    I wanted to try a bunka as a complement to my other knives. As an idea, what type of knife would it be if I only used one. And this is a very special knife in more ways than one. From the blade, it seems very beautifully traditional. If anything, it's a bit sturdy, but which makes for a good center up front. I normally like Aogami Super, but am more than surprised by the sharpness of this steel here. As far as I've been able to determine in the short time, it's not prone to chipping either. The handle is western, which I like, but at the same time pleasantly delicate. I have not found such a functionsl and aesthetic combination in any other knife series. Only the bunka flattening is perhaps not as pronounced as I had wished. It resembles with the slight rounding on the back still the Santoku from the series to a great deal. In the end this combination of blade and handle I liked so much that I already replaced my AS-Petty with one from this series and I'm afraid, sooner or later, I will probably also exchange my AS-Nakiri. Reason looks different, but this series is special and I like it.
