You can have any shape you like. There is no limitation as to what shape you can have other than staying within the maximum size limitations. Download the custom shape file above to see details of the maximum sizes allowed. Do not forget that you can have any shape you want but very fine details are not possible to cut on this type of product. We would not be able to create a blade for this. We will check your file and if we find problem, will get back to you right away.
