I have been storing this for a long time. As far as I can see with the untrained eye, there are no noticeable scratches or rust, but there may be some if you look closely. Please refer to the photos. *Please purchase only if you understand that returns and exchanges are not accepted. The most common stainless steel material is molybdenum steel, and all other materials have a high-grade sharpness and durability. Gin-san steel has both sharpness and durability, and is a material that is resistant to rust, so it is highly regarded by chefs. The handle uses a buffalo horn octagonal handle, making it very easy to use and designed to fit comfortably in the hand. The octagonal handle is easy to use, so much so that chefs say it fits comfortably in their hands.
