I do a lot of straight cutting that need pinking because of the unraveling of the fabric.  I used to sew a zig zag stitch around each piece.  Too much time and a waste of thread.  When I saw this item, I knew I had to have it.  I absolutely LOVE this it!!!  I was considering purchasing pinking shears; however, I didn't like the fact that the blades were heavy and that one cut did not cover a lot of material.  With this blade, I can cut long strips of fabric effortlessly!!!!  It cuts beautifully!!!!  I don't know why I didn't buy it sooner!!! I HIGHLY recommend this blade for all of your pinking
