Stainless steel is rust resistant, but less sharp than carbon steel.
However, most Japanese stainless steel blades are mixed with various steel materials to increase sharpness.
You will find that some stainless steel blades will retain its sharpness as much as those made of carbon steel.
Those stainless steel blades are not as rust resistant as blades made of 100% stainless steel.
They may get rusty if you store them without properly drying after use, or leave them without washing for a long period of time after cutting high acidic food such as lemons.
Stainless steel blades are recommended for those who do not want to spend time on maintenance as they do not rust as easily as carbon steel blades.
Please make sure you wipe water out and store it.
