What is the Kiritsuke Santoku/Bunka 180 mm suitable for?
The Kiritsuke Santoku/Bunka 180 mm is a versatile Japanese kitchen knife for both everyday and professional use. It combines the versatility of a Santoku knife with the more aggressive tip of a Bunka/Kiritsuke, allowing it to handle quick prep of vegetables, boneless meat, fish, and fruit, as well as detailed work with the tip.
The distinctive tip, inspired by a Japanese sword, allows for very precise finishing cuts, decorative work, and controlled cutting. The higher blade profile also supports comfortable chopping and rocking motions when slicing herbs or vegetables.
| Type of Use | Why the Kiritsuke Santoku/Bunka is Ideal |
|---|---|
| Vegetables | The wide blade allows for quick, precise, and clean slicing of larger quantities of ingredients. |
| Boneless meat | The thin geometry and SPG2 steel easily cut through muscle tissue. |
| Fish | A clean and controlled cut without damaging the delicate structure of the meat. |
| Fruit | The fine edge helps with precise slicing of both soft and firm fruits. |
| Herbs | The higher blade profile is suitable for rocking cuts. |
| Detailed work with the tip | The Bunka/Kiritsuke tip facilitates precise finishing cuts and decorative cuts. |
| Everyday cooking | The versatile shape handles most kitchen tasks. |
The Kanetsugu ZUIUN Kiritsuke Santoku/Bunka 180 mm feels exceptionally light, nimble, and very precise. The Hamaguriba convex grind ensures a silky-smooth glide through ingredients with minimal resistance and high control over the cut.
Why is SPG2 one of the best Japanese steels?
SPG2, also known as SG2, is among the most advanced Japanese powder steels used in premium kitchen knives. Thanks to its very fine microstructure, it achieves exceptional sharpness, high hardness, and long-lasting edge retention.
A hardness of around R63 HRC allows for very fine blade sharpening without compromising edge stability. The knife thus offers an exceptionally precise cut and longer intervals between sharpening.
| SPG2 Feature | Practical Benefit |
|---|---|
| Extreme Sharpness | The very fine microstructure allows for exceptionally precise sharpening. |
| Long-lasting edge | The knife retains its high sharpness significantly longer than standard stainless steels. |
| Edge stability | A hardness of approximately R63 HRC helps maintain a precise cut even with intensive use. |
| Lower cutting resistance | The thin blade geometry allows for smooth cutting through ingredients. |
| Premium cutting performance | Perfect for professional work, vegetables, meat, fish, and detailed cuts. |
Sub-Zero process – higher hardness and toughness
The blade undergoes a special deep-freezing process that promotes high hardness, material stability, and improved edge toughness.
| Advantages of the Sub-Zero process | Benefits for the knife |
|---|---|
| Higher hardness | The edge retains a fine sharpening better. |
| Better toughness | The blade is more stable during everyday use. |
| Longer edge retention | The knife requires less frequent sharpening. |
| More stable steel structure | Greater reliability for professional work. |
Hamaguriba – traditional Japanese convex grind
Kanetsugu ZUIUN uses the traditional Japanese convex Hamaguriba grind, inspired by the geometry of Japanese swords. The gently rounded profile helps achieve an exceptionally smooth and clean cut with less resistance.
Hamaguriba-ground knife selection
| Hamaguriba advantage | Benefits during use |
|---|---|
| Lower cutting resistance | Smoother and easier cutting. |
| Cleaner cut | Less damage to the structure of vegetables, meat, and fish. |
| Greater blade stability | Better resistance to micro-chipping. |
| Luxurious feel while working | Silky-smooth glide through ingredients. |
62 layers of Damascus steel
The blade features a multi-layered Damascus construction with 62 layers of stainless Damascus steel. The hard SPG2 core is protected by outer layers that ensure exceptional stability, toughness, and an elegant blade appearance.
The light damascene pattern minimizes friction during cutting while giving each knife a unique character.
| Damascene property | Advantage |
|---|---|
| Multi-layered construction | Greater blade stability. |
| Hard SPG2 cutting core | Extreme sharpness and long-lasting edge retention. |
| Protective stainless steel layers | Improved toughness and core protection. |
| Light-colored Damascus finish | Classic, elegant look of the ZUIUN series. |

Shichikaku – Ergonomic Japanese Handle

| Handle advantages | Benefits |
|---|---|
| Natural ergonomic grip | Less hand fatigue during prolonged use. |

| Ebony-colored pakkawood | Durable and elegant material. |

Recommendations and Maintenance for Japanese Knives
Never wash the knife in the dishwasher. Wash it by hand after use and dry it immediately.
Do not use the knife as a pry bar and do not bend the blade. The knife is intended solely for cutting.
Protect the blade and cutting edge from drops, impacts, and contact with hard materials.
If you will not be using the knife for an extended period, lightly coat it with oil and wrap it in a cloth or newspaper.
Store the knife in a safe place, ideally in a protective sheath, a knife block, or on a magnetic strip.
Keep the kitchen knife out of reach of children and exercise extreme caution when handling it.
Notice
Each knife is made from natural materials. Every piece of steel and wood is unique, so the final appearance of the knife may differ slightly from the product photo. The knife you receive will be of the same high quality and carefully crafted.
Sharpening a kitchen knife
To maintain maximum sharpness, we recommend regularly maintaining your Japanese kitchen knife using high-quality water whetstones, diamond whetstones, steel and honing steels.
Water stones are among the gentlest and most effective ways to sharpen Japanese knives. Diamond sharpening stones excel at rapid material removal, making them suitable even for harder types of Japanese powder steel, such as SPG2 / SG2.
Steel is primarily used for periodic edge alignment between sharpening sessions. For fine polishing and achieving extreme sharpness, we also recommend using stroping leather.
If you are unsure about sharpening, please contact us. We will professionally sharpen your knives according to your individual preferences. We also regularly organize knife sharpening courses.
Cleaning a kitchen knife
After each use, wash the knife by hand in lukewarm water, dry it with a soft cloth, and store it in a safe place. Residues of aggressive ingredients can cause rust-like stains on the blade’s surface. This is not always corrosion of the blade itself, but often food particles or debris from the surrounding environment that have become lodged on the surface. To remove them, you can use, for example, baking soda mixed with a little water into a fine paste and an old cork.
