Nisaku Japanese stainless steel blades do not rust, chip or stain easily, making them ideal for moist and damp environments. This is due to the chromium content in the material. They also do not require any protective or non-stick coating, meaning there is less chance of contaminating food if used in the preparation of edibles. Stainless steel is also one of the most recyclable materials, which supports our mission to remain eco-friendly. But the biggest attraction to stainless steel tools is that they maintain their appearance for a very long time and do not require much maintenance or cause you to make repeat purchases every season due to rusting or dullness.
