Fengyi Series · Anti-Blunt Knife is a high-end kitchen knife that blends traditional Chinese aesthetics with cutting-edge materials technology. With "lasting sharpness, becoming sharper with each cut" as its core appeal, the product features a unique black crystal titanium anti-dulling strengthening technology. Based on the principle of physical vapor deposition, titanium, aluminum, and nitrogen react in a vacuum environment to form a dense protective film on the blade surface. The knife employs a rigid-tough composite structure and a double-sided hardness difference self-sharpening system, combined with a high-quality stainless steel base and 3D arc polishing process, balancing ultimate sharpness and durability with an excellent grip. The design incorporates traditional Chinese elements such as flame patterns and phoenix decorative studs, symbolizing tempering for sharpness and bringing good fortune. It is an innovative kitchen utensil that combines cutting-edge technology with Eastern aesthetics.

Exceptional durability eliminates the need for frequent sharpening: Edge retention is improved more than sevenfold. The black titanium-coated surface offers high hardness, wear resistance, and low friction, minimizing cutting resistance and preventing dulling over time, which significantly lowers daily maintenance costs. Safe, rust-resistant, and perfectly balanced in hardness and toughness: Crafted from premium steel that resists corrosion and rust, the knife features a single-sided hardening design. This avoids the brittleness and chipping risks associated with overly hard edges, ensuring safe and reliable cutting. Self-sharpening technology—sharper with every use: A dual-sided hardness differential system allows the base material to wear down faster than the hardened edge. This causes the cutting angle to naturally narrow during use, enabling the blade to self-sharpen and maintain peak cutting performance. Ergonomic design for comfort and reduced effort: A smoothly polished, rounded 3D spine pairs with an ABS handle that feels soft and comfortable against the skin, ensuring a grip that won't dig into or hurt your hand. Perfectly balanced weighting allows for natural cutting motions, preventing hand fatigue during prolonged use. Aesthetic appeal and emotional resonance: Featuring a "flame" pattern inspired by traditional Chinese aesthetics and a phoenix-motif decorative rivet, the knife not only elevates the kitchen's visual style but also imbues the cooking process with a sense of auspiciousness and ritual.

The Fengyi series launched its pre-sale in July and August 2026, demonstrating immense market momentum right from the start. In July, the opening month of the pre-sale, the series achieved sales of 360 units across all channels. Momentum surged in August, with total monthly sales reaching 2,904 units—a month-over-month increase of 707%. Notably, the core product—the "Dull-Resistant" Slicing Knife—accounted for 1,656 of the August pre-sale units, marking a 1,050% month-over-month growth. Offline channels performed exceptionally well, accounting for 2,544 units (87.6% of the total) in August pre-sales and demonstrating strong sell-through capability at the retail level. Leveraging "Black Crystalline Titanium" dull-resistant technology and an aesthetic inspired by traditional Chinese style, the product successfully validated market acceptance during the pre-sale phase—even prior to mass distribution. This achievement marked a successful transition from a technical selling point to a market hit, laying a solid commercial foundation for the full-scale product launch on September 15.

Driving material and process upgrades in the kitchenware industry: It overcomes the industry's long-standing dilemma—where knives were traditionally either sharp but prone to chipping, or tough but prone to dulling—by offering an innovative solution that combines rigidity and toughness with a self-sharpening system, thereby steering the industry toward high-tech, long-lasting products. Promoting green, low-carbon, and resource-efficient principles: Its ability to maintain lasting sharpness without the need for frequent honing effectively extends the product's lifespan, reduces the frequency of replacements and metal loss from sharpening, and aligns with eco-friendly, sustainable consumption values. Championing cultural confidence through the "Guochao" (China-chic) ​​trend: By integrating traditional imagery—such as "forging a sharp edge through quenching"—and auspicious Chinese cultural motifs like the "Phoenix Bringing Good Fortune" into modern industrial design, the product promotes "China-style" aesthetics in everyday home life and strengthens consumers' sense of cultural identity.

Material Preparation: The blade is crafted from high-quality stainless steel (30Cr13 and 430 grades), ensuring excellent corrosion resistance, rust prevention, and high toughness. Core Strengthening Process (PVD): Utilizing Physical Vapor Deposition (PVD) technology, a chemical reaction involving titanium, aluminum, and nitrogen is induced in a vacuum environment to deposit a dense "Black Crystal Titanium" protective film on one side of the blade edge. Structural Design and Processing: The blade features a "Black Crystal Titanium" reinforcement treatment on one side of the edge (creating a black blade), while the other side retains the original base material, establishing a self-sharpening system based on the hardness differential between the two sides. Precision Finishing: The blade spine and bolster undergo a 3D arc-polishing process, resulting in smooth, rounded edges free of burrs. Ergonomic Assembly: The handle is injection-molded from skin-friendly ABS material, featuring an ergonomic curved design and precise weight balancing. Aesthetic Detailing: Precision engraving techniques are used to etch a flame pattern near the blade edge, while a phoenix-motif decorative rivet is inlaid at the handle's end.

R&D for this project officially commenced on May 13, 2026. Following approximately four months of highly efficient development, mass production was successfully completed, and the product was fully launched on the market on September 15, 2026. The transition from R&D to mass production was seamless, achieved within a tight timeframe. The total R&D investment exceeded 500,000 yuan.

The project progressed efficiently according to plan, with all milestones met on schedule: R&D commenced on May 13, 2026; production launched successfully on June 9; pre-sales began on July 1; and the full-scale market launch took place on September 15. In terms of technology and design, the team successfully mastered the "Black Crystal Titanium" PVD single-sided strengthening process, achieving a sharpness durability more than seven times that of standard kitchen knives and realizing a self-sharpening effect that enhances sharpness with use; additionally, aesthetic elements inspired by traditional Chinese culture—such as flame patterns and "Phoenix" rivets—were successfully integrated into mass production. From a market perspective, cumulative sales during the July–August pre-sale period reached 3,264 units, with August sales surging 707% month-over-month; offline channels accounted for 87.6% of sales, validating the strong appeal of the CMF design to end consumers and successfully achieving the project's commercial objectives.
