maybe a bearing somewhere... should get it checked.
i dont know if this will help you identify if it is a bearing, but if you hold up like a metal extension up to your ear and place the other end of the extension up to the engine, theres a chance you might hear a noisy bearing that may be at fault.
on another note.. my car makes a great loud rattling sound when you first start it, mostly when cold, not so much when warm. kinda like saying "Blah" but with rattling. i have no idea what in the world it is either....

Re: Cold start "knife on plate" sound (De_tour)
It sounds like the accessory belts may be either worn out or are not tightened to spec. Depending on the severity, the noise can go away in a matter of 2 seconds or after a few minutes of use. Check your A/C, P/S, and alternator belts with a tension meter (your local shop should have one, otherwise check with the dealership service dept). You may only need to tighten/loosen or replace the culprit belt(s). Worse case, it could be that one of the accessory pulleys needs to be replaced.
