When it comes to Japanese kitchen knives, few stand out like the Tanaka Kyuzo Blue 240 Gyuto. Known for its exceptional sharpness, elegant craftsmanship, and superior cutting performance, this knife is a favorite among professional chefs and passionate home cooks alike. In this article, we’ll explore the features, benefits, and reasons why the Tanaka Kyuzo Blue 240 Gyuto deserves a place in your kitchen.
What Is a Gyuto Knife?
“Gyuto” is the Japanese version of the Western chef’s knife. The word means “cow sword,” and it was originally designed to cut large cuts of meat. However, modern Gyuto knives are versatile tools used for slicing, chopping, and dicing vegetables, meats, and herbs with precision.
The Gyuto typically features a long, narrow blade that ranges from 210mm to 270mm. At 240mm, the Tanaka Kyuzo Blue 240 Gyuto hits the sweet spot — long enough to handle big tasks but still comfortable to control.
Who Is Kyuzo Tanaka?
Kyuzo Tanaka is a highly respected blacksmith based in Japan. With decades of experience, he is known for blending traditional forging methods with modern design. Every knife that bears his name reflects the heritage of Japanese knife-making. His dedication to handcrafting each blade ensures quality and performance that machine-made knives can’t match.
What Makes the Tanaka Kyuzo Blue 240 Gyuto Special?
Several elements come together to make this knife truly outstanding. Let’s break down the features that make it a favorite among kitchen professionals.
1. High-Quality Blue Steel Core
The core of this knife is forged from Blue Paper Steel (Aogami) — one of the best carbon steels available for kitchen knives. Blue steel is known for holding an edge longer than many other materials. It is hard, fine-grained, and sharpens easily.
This makes it perfect for chefs who demand razor-sharp precision. Whether you’re slicing sashimi or julienning vegetables, this knife performs beautifully.
2. Clad in Soft Iron for Strength and Beauty
The Blue steel core is clad in soft iron using a traditional technique called “kasumi.” This layering gives the blade added toughness and a beautiful visual contrast. The gentle wave pattern on the blade is not just decorative — it’s a mark of its hand-forged origin.
This soft cladding also makes the blade easier to sharpen and less likely to chip, making it more forgiving during intense prep work.
3. Hand-Forged Craftsmanship
Unlike mass-produced knives, each Tanaka knife is hand-forged. This involves heating, hammering, shaping, and polishing — all done by hand. This craftsmanship ensures that every blade has a unique personality and attention to detail.
Forged knives also tend to be stronger and more balanced than stamped knives. The time and skill required to make one reflect in both performance and price — but for many, it’s well worth the investment.
4. Comfortable and Functional Handle
The Tanaka Kyuzo Blue 240 Gyuto often features a traditional wa-handle, typically made of hardwood such as walnut or magnolia. This type of handle is lightweight and offers excellent grip and control. The octagonal or D-shape fits well in the hand and suits both right-handed and left-handed users.
The balance point between the blade and handle is carefully crafted for long periods of use without fatigue.
5. Versatility in the Kitchen
At 240mm, this Gyuto knife is an ideal size for all-around kitchen tasks. It’s long enough to handle large pieces of meat or fish, yet still precise for mincing garlic or chopping herbs. The slim profile and light weight make it agile and efficient.
Whether you’re cooking Asian cuisine, French dishes, or simple home meals, this knife can handle it all.
How to Care for the Tanaka Kyuzo Blue 240 Gyuto
Because this is a high-carbon steel knife, it’s important to care for it properly:
- Keep it dry: After each use, wipe the blade clean and dry immediately.
- Use a cutting board: Never use it on hard surfaces like glass or marble.
- Sharpen regularly: Use a whetstone to maintain the edge.
- Oil the blade: Occasionally apply camellia oil to prevent rust.
With proper care, this knife can last a lifetime — and even improve with age.
Is It Worth the Price?
Yes — if you’re looking for a tool that combines precision, durability, and beauty, the Tanaka Kyuzo Blue 240 Gyuto is a wise investment. While it’s not the cheapest knife on the market, its performance far exceeds standard kitchen knives.
This is a knife for people who value the art of cooking and understand the importance of high-quality tools.
