The contour curved handle enhances grip comfort and safety, while the classical triple rivets add to the handle's durability and traditional aesthetic. Hi-Density Blackwood and Durable Handle, Reduces Fatigue and Stain-Free. High-density Blackwood, originally from West Africa, is a strong, resilient material that withstands regular kitchen use.
Its ergonomic design minimizes hand fatigue, and being stain-free due to high density, it ensures ease of cleaning and maintenance for hygienic food preparation. 57-59 Rockwell Hardness with 15-17 Edge Angle Degree, Outstanding Cutting Performance. A Rockwell hardness of 57-59 offers a good balance of blade flexibility and strength, making it suitable for various cutting tasks.
The 15-17 degree edge angle, deemed as "Golden Angle" of a knife, provides a sharp, precise cutting edge for efficient slicing, chopping, and dicing. Oil-Hardened Blades, Remarkably Sharp, Stay Sharper Longer, Highly Corrosion Resistant. Oil quenching heat treatment (Oil hardening) involves heating the knife and then rapidly cooling it in oil. The advantages of this process include preventing prolonged exposure to air, which controls the formation of surface oxidation layers. Oil quenching also results in higher hardness (1-2HRC higher) compared to air cooling in the same temperature range.
The oil used in the quenching process covers the blade surface, preventing oxidation and resulting in better toughness and rust resistance compared to conventional heat treatment.
