How do the Reavers keep their gorram ships running?

I have enough problems keeping my firefly class transport working, and that's with a damn fine engineer working full time on her. The Reavers don't seem to use any tools more complex than blades and I can't imagine them being able to understand what to do them, even if they had them.

Reavers will attack any ship they can, and because they are so savage, they prefer to board the ship and kill the crew with their bare hands.  Afterwards they have a perfectly maintained ship filled with supplies.  

So its not that they maintain their ships better than you, its just that their life style gives them a never ending supply.
