The Blades

The blades in this Japanese kitchen knives set are designed to make cooking more enjoyable as cutting through produce will become an effortless task.
The blades in this Japanese kitchen knife set are handcrafted by skilled Japanese blacksmiths in Sakai, Japan with premium Japanese VG10 stainless steel. VG10 is a stainless steel with a high carbon content, making it harder than most stainless steel types. With VG10,  you get the hardness of a carbon steel but the corrosion resistance of stainless. Hence, VG10 steel offers an excellent balance between toughness, durability, and a razor sharpness.
The blades have a Rockwell Hardness rating (HRC) of 62 which means the edge stays noticeably sharper for a longer time. This means you won’t have to worry about sharpening them often. They are forged with 46 layers of Damascus steel which is legendary for its plasticity, hardness and distinctive patterns. The blades will allow foods to be easily and promptly cut with precision.

The Handles

The beautiful handles are made with extremely limited European maple burl dyed in an Olive Green colour and feature a subtle copper ring under the oak bog wood kakumaki (collar of the handle). The wood has to be dried for two years before it undergoes the process of stabilisation. This ensures the wood is completely waterproof to avoid bacteria growth and is able to last generations.

The Japanese kitchen knife set’s kakumaki (collar) is made with oak bog wood. A wood ranging from 2,500 to 5,000 years in age. Its age and living conditions give it a unique character and rich natural colour variation determined by its age. Giving you a knife with a rich history.

The stabilised premium-cut maple burl is shaped into an octagonal shaped ambidextrous handle to give you a firm grip on the knife. Not only are the handles aesthetically pleasing, they are also perfectly balanced, light and comfortable. This allows for maximum precision and more controlled movements during use.

Please note that no two handle colours or patterns are ever the same as the natural properties of each wood block are unique and will absorb the colour dye differently. This will give each knife a beautiful unique look.

The Packaging

All Sakai Kyuba kitchen knives set come in a handcrafted, minimalist European Oak wooden box with a delicate waxed finish. The box is wrapped in a Oishya signature illustration strip presenting the Onna Bugeisha – Japanese female warriors.
Inside, you’ll see a beautiful note with a genuine 5 Japanese yen coin for luck. There’s an ancient superstition that giving someone a knife is bad luck because it cuts the relationship between the giver and the recipient. The way around this is to attach a coin of symbolic value to the knife, which is then returned to the giver as a form of payment. As we want you to maintain your relationships with your loved ones, here is a 5 yen coin. 

The Japanese for five yen go en (五円) is a homophone with go-en (御縁), which means relationship, connection and bond. So by exchanging this coin with the receiver you no longer have to worry about this superstition.

Who is Sakai Kyuba 堺久馬?

Sakai Kyuba knife making process blacksmiths

Sakai Kyuba  堺久馬 is the name of our line of Japanese kitchen knives. Under the Sakai Kyuba 堺久馬 brand lies the artistry of one of the most famous blade masters in Sakai (Osaka Prefecture), Japan, drawing from over 600 years old blacksmithing tradition.

Our blacksmith established himself in 1927 and combines Sakai’s centuries-long history of knife making knowhow with newer technologies to create superior knives. In other words, he is devoted to honouring Sakai’s rich knife making history techniques whilst making improvements to create truly unique, innovative, and one of a kind knives. He is known for making knives for multiple users such as household users, cooking schools and chefs.
At Oishya we spent years searching for the ideal Japanese blacksmith to make our blades. Once we finally found him we encountered a problem. Due to geolocation exclusivity reasons, the blacksmith’s name couldn’t be included in our knives. We weren’t willing to let go of his outstanding artistry that easily, so together we created these knives under our dedicated brand name “Sakai Kyuba 堺久馬” .To make the knives even more unique, a team of talented European artisans is chosen to make the colourful maple burl handles.

What are Sakai Kyuba 堺久馬 blades made from?

Sakai Kyuba knife making process hammering
Sakai Kyuba blades are handcrafted with the premium Japanese VG10 high-carbon stainless steel by a skilled Japanese blacksmith in Sakai, a small village in Osaka.VG10 is a cutlery grade stainless steel, the name stands for V Gold 10 (“gold” meaning quality). It offers an excellent balance between toughness, durability, and razor sharpness. It has higher carbon content than some other premium brands, which helps the edge stay noticeably sharper for a longer time.Our blades are 46 layers of Damascus steel. To form a pattern at least two different steels are forged welded together (hammered together at forging temperatures) and then folded multiple times to produce layers.
Sakai Kyuba blades are sturdier and sharper than anything you have experienced before. They will cut through food with ease making your time cooking more enjoyable and relaxing.

Where are Sakai Kyuba knives made?

Every single Saki Kyuba  堺久馬  blade has been meticulously handmade, forged and hand-polished in Japan by master craftsmen in Sakai. Whilst the beautiful handles are crafted by artisans in Europe using limited European maple burl.

How long will my knife stay sharp?

This really depends on how often you use the knife, how you care for it and what items you’re cutting. In general, Japanese knives tend to hold their edge longer than Western knives. In other words, Japanese knives stay sharper longer than their Western counterparts. When tested, Sakai Kyuba knives outperformed brands that cost much more. We estimate that for a person cooking 5 times a week, Sakai Kyuba knives will stay sharp for around 4-8 months. However, no knife — including ours — will stay sharp forever. Which is why we provide a variety of sharpening stones, so when the blade starts to dull, you can sharpen it easily at your home in 5-10 minutes. Otherwise, check out our recommended trusted knife sharpening services.

Does it make sense to buy one knife first, and not a set?

If you can’t afford or do not want to commit to buying a set immediately, the single most important tool in your kitchen is The Gyuto – The Chef’s Knife. It’s the workhorse you reach for most often. Investing in one great knife now will change your cooking for life and make it a pleasure rather than a chore. Our Sakai Kyuba Gyuto can do 99% of your kitchen cutting. Another option for a daily knife is Santoku knife. However, if you’re looking for an ultimate experience, you should consider investing in a 3-pieces set; including The Petty (Paring/Utility Knife), Nakiri (Veggie/Fruit Knife) in addition to The Gyuto (The Chef’s Knife).

Do these knives require special care?

Sakai Kyuba knives are extremely durable and easy to care for. However, any knife, even a premium one needs sharpening at some point. As a good habit, you should sharpen them regularly and dry them immediately after use. These are 3 general rules you should follow:

  1. Don’t put your knife in a dishwasher.
  2. Store your knives either on the magnetic knife strip, knife stand, or sheathed in the utensil drawer.
  3. Don’t slide your knife, blade down, across the cutting board to clear away what you just chopped.

Also, check our full guide on how to properly maintain the knife and sharpen it.

What is oak bog wood?

bog oak

Bog wood comes from trees that have been buried in peat bogs and preserved from decay by the acidic and anaerobic bog conditions. This wood ranges in age from 2,500 to 5,000 years. Bog oak is known for its exceptional strength and often used to make luxury furniture and interiors.  Its age and living conditions give it a unique character and rich natural colour variation determined by its age. Its colour gradually darkens with age going from a light, golden brown to an almost ebony-black colour.

    Fantastic set of knives every cook should treat themselves too.
    I was looking for a new knife set, my old set was almost 20 years old and struggling to retain a sharp edge so after spending a good bit of time researching knifes and in the end I opted to go Japanese and purchased the 3 Sakai Kyuba x Oishya set. They are not cheap!

    The knifes are beautiful to look at, light to handle and gosh they are sharp. They make preparing food a pleasure the ease they slice through vegetables and meat is incredible. After using these I’ll never be able to use a cheap knife again to cook. There is a saying in life you get what you pay for and buy cheap buy twice. They are expensive but if you enjoy cooking they are absolutely worth it.

    The quality of these handmade knifes is fantastic!! The customer support is super quick, helpful and friendly. I really love the history of the female samurai behind the knifes. It’s run by women competing in a Male dominated field. I really love to support them 🙂
