Sakai Takayuki 45-Layer Hammered Damascus 240mm Gyuto (AUS-10 Steel)
The Professional Workhorse: 45-Layer Damascus 240mm Gyuto
The Sakai Takayuki 45-Layer Damascus 240mm Gyuto is a professional-grade masterpiece designed for those who require maximum reach and efficiency in the kitchen. Forged with a premium AUS-10 Stainless Steel core, this knife offers an exceptional balance of edge retention and toughness. AUS-10 is highly regarded by chefs for being more resilient and less prone to micro-chipping than other high-carbon stainless steels, making it the ideal choice for a 240mm "workhorse" blade.
The blade features a hand-hammered Tsuchime finish, which reduces food friction and prevents sticking, while the traditional Magnolia Wa-handle with a Buffalo horn ring provides a lightweight, front-balanced feel. This allow the knife to do the work for you, whether you are slicing through large proteins or prepping crates of vegetables.

Maintenance & Long-Term Care
Pro Tip for Longevity: Because a 240mm blade has a larger surface area, proper storage is critical. We recommend a Magnolia Wood Saya or a felt-lined Knife Protector. This prevents the high-performance AUS-10 edge from chipping and protects the 45-layer Damascus finish from scratches when stored in a drawer or knife roll.
Sharpening Maintenance: AUS-10 steel is highly prized for its "sharpenability." To maintain this blade's surgical edge, we recommend a Double-Sided 800/6000 Grit Whetstone. The 800 grit side refreshes the geometry, while the 6000 grit side provides a mirror-polished finish that glides through ingredients.
Performance & Care
-
Best For: Large-scale prep, slicing medium to large proteins, and heavy vegetable work.
-
Care: Hand-wash only with mild soap and dry immediately. Never use a dishwasher, as the high heat and chemicals will damage the natural Magnolia wood and Buffalo horn.
-
Safety: Avoid cutting bone, frozen foods, or hard pits; the precision-ground edge is optimized for fine slicing and can chip if used on hard materials.
Frequently Asked Questions
Why choose a 240mm Gyuto over the standard 210mm? The 240mm (9.4") length is the preferred choice for professional chefs. The extra length allows you to slice through larger ingredients (like a whole brisket or a large head of cabbage) in a single stroke, and the slightly more forward balance makes the knife feel more powerful during heavy prep.
How does AUS-10 compare to VG-10 steel? Both are premium Japanese stainless steels. However, AUS-10 is often preferred for larger knives because it is slightly "tougher" and more resistant to micro-chipping than VG-10. This makes it more durable for the high-volume work typically performed with a 240mm blade.
What is the benefit of the Buffalo horn bolster? The Buffalo horn ring is a traditional sign of a high-quality Wa-handle. Beyond its beautiful aesthetic, it is a dense, natural material that provides a seamless, hygienic transition between the wood and the blade, preventing food particles from entering the handle.
