Could someone please tell me how I can make an object's surface appear like Chrome / SIlver? I want it to look like this:

Notice the crisp edges within the reflection i.e. between the black, grey and white highlight. This is the kind of look I'm looking for. i have seen some other Chrome tutorials but they give a rather blurred chrome effect. If someone could please post a screenshot of their Material Room settings which would give the above Chrome effect, that would be superb! Thank you
