I use the Silhouette every day in my bakery. I print on gum paste, not icing sheets so I have to use the blade for gum paste. If you are only going to be cutting icing sheets, then the blade that comes with the Silhouette will be fine. You can adjust the depth of the blade to cut thicker materials, like icing sheets. If you want to do more that cut icing sheets, then you really need to invest in the kit from Linda McClure.
