I purchased this item new in May 2020, based on its high ratings on a comparison website, and used it for about a year to cut plastic bottles. After that, I rarely used it and kept it in a kitchen drawer. Upon close inspection, there are some scratches on the blades, but the sharpness is still reasonably good. I have never cut anything harder than a plastic bottle with it. - Brand: Kinzoku Kogyo Seisakusho - Model Name: Kitchen Scissors, Stainless Steel - Uses: Cooking, Scissors, Kitchen Tool - Material: Stainless Steel Thank you for looking.
