When I was a teen I worked at McDonald's. It was back in the McDLT days when we had to slice tomatoes and had a slicer like this. This slicer is jusy like that. It is efficient and easy to use.Note the width is a bit thin. I like the tomatoes that way but if you don't want pretty thin get the next bigger width.You will want a $5 tomato corer to use with this to cut out the top green part.
