If the tools are mase of metal containing iron then they will rust, especially if wet. This is caused by oxidation of the iron by oxygen in the atmosphere (or dissolved in water) to form soft iron oxide.

Metals get rust because of oxygen. To explain, when air (which has oxygen in it) is able to get to the metal after a period of time rust starts to appear (Rust is also called iron oxide. So rust appears only appears on iron.)

When a drop of water hits an iron object, two things begin to happen almost immediately. First, the water, a good electrolyte, combines with carbon dioxide in the air to form a weak carbonic acid, an even better electrolyte. As the acid is formed and the iron dissolved, some of the water will begin to break down into its component pieces -- hydrogen and oxygen. The free oxygen and dissolved iron bond into iron oxide, in the process freeing electrons. The electrons liberated from the anode portion of the iron flow to the cathode, which may be a piece of a metal less electrically reactive than iron, or another point on the piece of iron itself.
