This double-sided cutter provides two cutting profiles, allowing you to create either a smooth round edge or a decorative wavy edge from the same tool. It can be used with pastry, cookie dough, sugarpaste or rolled fondant, gum paste, marzipan, and suitable craft clays. The cutter is useful for shaping pastry pieces, cookie decorations, cake plaques, swags, decorative fabric effects, and cupcake toppers. When used for both edible and non-food projects, the packaging advises keeping food-use tools separate from those used with craft materials.
