Detailed Description

The Master Grade I.O. Shen 3073 is a 9-inch (240 mm) professional chef's knife built for precision, durability, and all-purpose kitchen performance. At its core is the proprietary Triplex Steel Technology, where a layer of super-hard ERDON steel (Rockwell 62) is sandwiched between two layers of softer stainless steel (Rockwell 10), eliminating brittleness while delivering a razor-sharp edge with extraordinary retention. Each knife is meticulously handcrafted by a master knife artisan over an average of 7 hours, ground to a precise 15-degree angle and finished with a mirror-polished cutting edge. The full Tai Tang construction integrates the handle frame for superior balance, while the durable, heat-resistant ebonite handle features a distinctive Yin Yang-inspired design that sets it apart from any other chef's knife on the market.
