To use this bread slicer, first find a suitable blade that fits it. Place the bread on the slicer's platform. Then, carefully push the bread through to get your desired slices. When it comes to maintenance, keep the metal parts clean and dry to prevent rust. Wipe the wooden parts gently with a soft cloth. Be cautious when handling the slicer, especially if you're attaching a new blade. Avoid using it on very hard or large - sized bread that might damage the slicer. Store it in a dry place when not in use.
