After yers of research for the ultimate performance kitchen knives in functional materials and design, Mr. Kawamura of Kanetsugu has released the innovative line of Pro J Series.
Hammer Forged Tsuchime Blade has cladding blade construction. Blade core is made of special high grade Cobalt steel called ZA-18 from Aichi Steel Company, sandwiched with AUS-2 stainless steel. This is the first kitchen knife to use this new formula steel of ZA-18.
Mr. Kawamura explains Aichi Steel Ccompany has recently developed this ZA-18 to compete or even outperform VG-10. It is heat treated and then ice hardened (Sub-Zero quench) to the Rockwell hardness of HRc. 60-61. The Chemical Composition of ZA-18 is similar to the VG-10, but contains higher Carbon (1.20 vs. 1.05), Chromium (18.0 vs. 15.5), Molybdenum (1.50 vs. 1.20) and Cobalt (1.80 vs. 1.5) for added hardness, durability and rust-resistance. In fact, before Mr. Kawamura decides to use this steel for Pro J Series, he has tested it many times and proved it's incredible cutting performance and potential. Japanese technology of the cladding blade construction also has many advantages in the durability and maintenance, because the AUS-2 outer steel protects the core steel, and makes the blade extra strong to bending and breaking for the different hardness steel layers.
The handle is made of Black-Pakkawood handle, comes with nice accent of red color micro fiber spacer and stainless steel bolster. It is ergonomically designed with slightly slanted bolster forge welded into the tang and full tang hand rounded handle slab to fit with your hand.
