Knife Blog

I will explain about stainless steel in this blog since I explained about carbon steel in another blog. Stainless steel that is strong for abrasion and hardly gets rusted is made when chrome is added on steel. Carbon steel can create sharper knives, but stainless steel hardly gets rusted, so it is becoming popular now.
 
Gingami III is mostly used for Japanese knives among stainless steel Hitachi Metals, Ltd creates. (Hitachi Metals makes white steel and blue steel that are main materials for Japanese knives.) Gingami III has hardness like carbon steel knives. And Gingami III is viscous, so it might be hard to sharpen Gingami III knives, but among stainless steel Gingami III is easier to sharpen and hardly gets rusted.
 
Other than Hitachi Metals, Ltd. Takefu Special Steel CO., Ltd also manufactures stainless steel.
 
The basic stainless steel is VG1. It contains molybdenum and the amount of carbon is 1%, so this realizes hardening with a high hardness. VG1 knives hardly get rusted and make us cut for long time. “V” of VG1 means virgin steel.
 
VG10 is made when carbon, chrome, molybdenum, vanadium, and cobalt are added on high-selected virgin steel. VG10 knives hardly get rusted and enable us to cut for long time. Rare metals, cobalt creates high hardness and high abrasion resistance.
 
I introduce 1 more stainless steel and 1 more material.
 
Molybdenum steel is created when molybdenum and vanadium are added on stainless steel. Molybdenum increases high abrasion resistance and vanadium prevents steel from being soft and increases viscosity.
 
There is High-speed steel, which is manufactured by burning and settling powdered materials at metallurgic process of manufacturing. High-speed steel is very hard and has fine compositions. High-speed steel is said to be excellent in terms of hardness, sharpness and durability.
