Product Description

The Santoku

If you’re looking to invest in one good quality knife, then you should be looking at a Chef’s knife: a Gyuto or Santoku knife. While specialised knives may be easier to use in some applications, there are few chores that a Santoku cannot do in a pinch.

Santoku translates to “three virtues”: slicing, dicing and chopping. You can utilise a Japanese Santoku knife in most recipes that call for knife work, as they are true all-purpose workhorses.

Sakai Kyuba – Chef’s Knife 19cm The Santoku – Olive Green

Stabilised premium-cut limited European maple burl

Octagonal shaped ambidextrous handle for a firm grip

Subtle copper ring

Oak bog wood kakumaki

Forged with 46 layers of Damascus steel

Premium Japanese VG10 high carbon stainless steel

Some (especially women who usually have smaller hands) consider Santoku to be more agile than Gyutos as they fit more comfortably in their hand due to their size. Santoku knives are usually shorter than long chef knives (less than 21cm) and have wide, flat blades and fairly blunt or slightly rounded tips. This helps combat hand fatigue and compensates for the fact that you have to actually chop and not rock.

The Santoku knife is comfortable, light, and fast. Its double bevel makes it perfect for both left and right-handed use. A knife as unique and everlasting as the memories you will create using it.

The blade

The blade in this Japanese Santoku knife is designed to make cooking more enjoyable. Cutting through produce will become an effortless task.

The santoku blade is 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 knife blade has 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 it often. It is forged with 46 layers of Damascus steel which is legendary for its plasticity, hardness and distinctive patterns. The blade will allow foods to be easily and promptly cut with precision.

The handle

The beautiful santoku knife handle is 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 is 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 knife’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 is the handle aesthetically pleasing, it is also perfectly balanced, light and comfortable. This allows for maximum precision and more controlled movements during use.

The packaging

All Sakai Kyuba knives come in a handcrafted, minimalist European Oak wooden box with a delicate waxed finish. The box is wrapped in an Oishya signature illustration strip presenting the Onna Bugeisha – Japanese female warriors.

What is Sakai Kyuba 堺久馬 ?

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 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.
