Where did you get that picture? That is what it is. I didn't realize you had to cut in between the lines. I thought it was something that sliced like an egg slicer. I think you are right. Thanks.
I don't know what it would be used for. There are no cutting blades. It doesn't slice an egg or anything. My sister has never used it and doesn't remember who she got it from. She doesn't think it had any other pieces that go with it.
