All food processors will come with basic cutting blades. A slicing blade (2mm and 4mm) is useful for automatically cutting up vegetables and fruit, into a uniform size. Grating blades help you get through a lot of grating fast, which is great if you’re making a cheese-based dish or need a lot of grated potatoes, for example. Other blades can seem like a good idea, but you may use them rarely. A julienne blade can be useful for slicing vegetables into sticks, but it isn’t the kind of thing you’d use on a daily basis. Likewise, a French-fry cutter and citrus juicer may just take up space in your cupboard.
