What do you plan on using it for? I have a tool for marking 1/4 inch seam allowances. It is about 12" long but only 1/4" wide no matter which side you use for measuring. I have another 1/4" tool that is flat with several oblong holes cut in the center. This one is used for marking squares to be cut for 1/4" triangles. I don't know of any tools that are only a 1/4" wide and designed as a cutting guide.
