*This knife is made from a three-layer steel of ZDP189 and SUS420J2. Despite being three-layer steel, it has been thoroughly hardened, boasting a hardness comparable to honyaki knives. The core ZDP189 reaches HRC67, while the SUS layer is 62±1, making it extremely hard and difficult to sharpen. As a result, this knife is challenging for beginners to handle.

  • What captures global attention is how our knives communicate their excellence and beauty at first glance.

  • When you first lay eyes on a Sakai knife, something speaks to you even before you touch it. The way light plays along the blade's surface tells a story of countless hours of meticulous craftsmanship. It's like seeing a masterpiece painting—you don't need to understand the technique to recognize its beauty. The same holds true for our knives: their quality is evident whether you're a professional chef in Paris or a home cook in Singapore.

  • Excellence has a universal language. When someone picks up one of our knives, there's often a moment of silence—that instant of recognition when they feel something extraordinary in their hands. The perfect balance, the seamless transition from blade to handle, the way the edge catches the light—these qualities transcend cultural and linguistic barriers.

  • But it's when they make their first cut that the true magic happens. That clean, effortless slice through an ingredient often brings a smile of amazement, regardless of whether they're in a Tokyo restaurant or a New York kitchen. This immediate, visceral understanding of quality is why our knives have found homes in kitchens across the globe.

  • Our craft speaks through performance and beauty rather than words. In a world where authenticity is increasingly valued, these knives carry an undeniable truth in every aspect of their creation. That's the real reason they've captured attention worldwide—because true excellence needs no translation.
