GLOBAL Sai Knives Designed by Korin Yamada follow the GLOBAL quality line, the most important difference is in the manufacturing and structure of the blade:
 Blade made of 3 layers, this allows for a sharper blade since it is made with 2 different types of steel and the maximum performance of each type of steel is obtained.
 The central layer (cut) is made of Cromova18 stainless steel
 The outer layers (one on each side) are made of stainless steel. These outer layers protect the middle layer from rust, stains, scratches, etc.
 The cutting edge has been polished, this detail gives a superior edge and maintains the edge for longer.
 The blade has a hammered finish known in Japan as Tsuchime, which is not only aesthetic, it also provides better sliding of the blade when cutting.
 Blade hardness: 58-59 HRC
 The handle follows the line of a hollow, ergonomic handle with GLOBAL's characteristic black "dots".
