It depends on the tool, but it is possible. If you own a stainless-steel tool, then there is a strong possibility it won’t rust. Of course, fiberglass and wood won’t rust, but wood could warp. Aluminum and other materials have a chance of rusting. To avoid rust you should keep your tools stored in a dry place, never expose them to rain and snow and be sure you dry them off immediately after they get wet. Your care manuals will tell you whether your tools are rust resistant or not, and they will tell you how to care for your tools properly to avoid rust.
