Sandwiches can be utensil hogs. One knife for slicing the bread, another for spreading the butter, a third for slicing the cheese and meat, and a spoon for the mayo.
Made from durable textured plastic, the Tupperware Sandwich Spreader does it all, and more. Slice and spread an avocado, and get as much jam and peanut butter out of the jar as you want.
25cm long. Only comes in ivory, not the pale green shown in the photo and video.
