The precision stainless steel blade can adjust to eight different heights easily with a twist and locks in place, allowing you to trim off the top of the cake so it's level and to cut the cake into thinner layers and put icing or filling between for a multi-layered, torted cake. While it folds for easy storage, the sliding sleeve locks in place over the hinge so the two ends work as one long blade, slicing through your cake evenly and smoothly. And the ergonomic handle makes slicing through the cake easy. Blade is long enough to cut through an 18-in. cake. 8 blade setting: ¾ in., 1 in., 1 ¼ in., 1 ½ in., 1 ¾ in., 2 in., 2 ¼ in. and 3 in.Complete instructions included. Wipe blade clean with damp cloth and dry thoroughly.
