After each use, remove any dirt, sap, or debris from the blades and handles. Use a brush or cloth to clean them thoroughly. Regularly sharpen the blades with a sharpening stone or tool to maintain their cutting efficiency. When not in use, store the garden shears in a dry place to prevent moisture and rust. You can hang them or keep them in a tool shed or storage container. Garden shears are designed for specific tasks, so avoid using them on materials that are too hard or thick, as this can damage the blades.
