KitchenAid does not manufacture a bread slicer or bread slicer attachment for any of its products, as of March 2015. Kitchen supply retailers and websites like Amazon.com supply a variety of bread slicers and bread slicing accessories designed for home use. Alibaba.com offers equipment designed for business use.
Bread slicing equipment ranges from a blade guide for slicing bread to fully automated slicing machines that cut an entire loaf at once. Intermediary options, such as electric bread knives and food slicers, are also available. Inspect products carefully, because some websites may list KitchenAid in the product description when it is not actually a KitchenAid brand product.
Contacting KitchenAid's customer support may encourage them to manufacture a branded bread slicer. Contact information is available at KitchenAid.com.
