I am looking for a tool that divides in even segments. It can be stretched out like an accordion to make different widths but still keep equal separations. Is there someone who can tell me what this tool is called and where to purchase one?
I think you are referring to a pastry cutter. They come in multiple sizes and number of wheels. I have a 6 wheel cutter from Instawares that is great.
