It depends on the kind of scissor that you purchase. We have scissors available that have been manufactured with an anti-rust coating, such as our Midnight Edition line of fabric scissor, or are crafted from an anti-rust material, such as any of our stainless steel tools. Others will need to be coated with oil, such as a sewing machine oil, if they're being stored for a couple of months. Just like a knife, as long as you are keeping your scissors clean and dry, you shouldn't experience any issues with rusting.
