To use this bread slicer, simply place the bread on the slicing area and use the handle to guide the blade through the bread for even slices. When handling it, be careful of the sharp blade to avoid injuries. For maintenance, clean the slicer with a dry cloth after each use. If there are any food residues, you can use a damp cloth, but make sure to dry it thoroughly to prevent rusting, especially since it has metal parts. Store it in a dry place when not in use to keep it in good condition.
