I love this little Spiralizer Kitby Procuisine!The kitincludes the spiralizer, 4 blades, peeler, knife, cleaning brush and a 101 recipe ebook. The blades are made of stainless steel. The knife and peeler look like plastic but are both sharp and very strong. the knife cut through and apple and potato like butter and the peeler worked right too. I am glad to have this set for my new healthy eating lifestyle. The easier to prepare the better. This has saved a lot of time in the kitchen as well. I would recommend and be interested in seeing more products from procuisine. i received this product for free in exchange for my complete and honest review.
