Very positively surprised by the effectiveness of this sharpener. It attaches very well to a support (smooth) which frees hands and helps sharpen all types of knives (perhaps less those very fine serration). I had considered buying new kitchen knives but there they found their youth. Whether for meat knives, bread or just those we met at the table for lunch or dinner, this little wonder the sharpens all perfectly again, AnySharp ranks easily in the kitchen drawer saw its height. I am very pleased with this purchase and can only recommend.
