Query: Are blades stainless steel?

It is a good product & it did simplify our cooking. The recipe book is nice too. The part of the product which I do not like is that the blades are not stainless steel but made of metal. Put a magnet against the blade & it will stick. After a month of use, one of the blades developed a rust spot.Remember to dry the blades such that no water spots remains on it after washing it else you will have rust spots on your blades."
