Use Mrs. Anderson's Bread Slicing Guide to cut even slices of homemade bread. Place the loaf on the wood base, against the back panel, and slide the knife blade between the slots in the acrylic panels to slice the loaf. Remove the back panel when slicing longer loaves. Crumbs fall through the slots in the wood base, and can be removed by sliding out the crumb catcher. Made from wood and acrylic. Wipe clean.
