To keep your cutting tools for sewing sharp for as long as possible, clean them of lint and dust before and after work. Store your cutting tools for sewing in a case in a dry place horizontally. Do not use the cutting tool to work with materials for which it is not intended. Do not cut wet fabrics, the blade of your cutting tool may become covered with rust and your tool will become unusable. These simple rules will allow the blades of your tool to stay sharp for as long as possible.
