Will the Fractal Vise rust? Can it get wet?

The Fractal Vise is primarily made from non-ferrous materials and features stainless and treated steels that stave off rust.

If you're using your vice for wet drilling and need some liquid action, there's no problem with your Fractals getting well acquainted with fresh water as long as you dry it off after use. You'll want to avoid any kind of salt water on your Fractal Vise. 

As with all tools, if you look after them they will look after you.
