Actually, you are advised to clamp the negative jumper cable to a steel component like the Alternator bracket or a bolt on the engine or any part of the cars frame. This has nothing to do with blowing a fuse. When a Lead/Acid battery is charging, it releases Hydrogen gas that vents out of the battery through vent holes designed for that purpose. Some gas can build up inside the battery and when you remove a jumper cable you might make a spark and it is possible for the battery to explode. Obviously, this isn't good for the battery but more importantly it might cause battery acid to spray into your eyes or onto your skin and harm you. Be careful.

If you're talking about jump starting a car from another car... Connect both car's positive terminals together, then both car's negative terminals together. Your question was a little goofy. Metal is the only way to MAKE the electrical contact between the cars generally speaking. So it sounds to me like you got your comment from someone who might not know what their talking about. Blowing a fuse isn't really an issue when connecting the electrical systems of 2 cars together. I've never known it to happen. If you REVERSED the polarity when connecting... that's when the bad things start to happen. Make sure I'm not near if you ever do this please.

Why do all the Experts know nothing?
Keep the hood of both cars open so Hydrogen cannot collect.
Check that each of the six cells in the "DEAD" battery have water above the plates. Add only "Distilled" water such as is used for steam irons... Do NOT overfill!!!
Connect Red to Positive on each battery.
Make tight connections.
Make Black connection to "DEAD" battery.
Step back eight feet to good battery.
Start and let idle car with good battery.
Connect Black wire to Negative battery post and rev engine to 1000 RPM (Fast idle) for two minutes.
Then crank car who's battery was "DEAD."
Disconnect wires in reverse order.
If battery won't start car in 10 minutes, have battery and charging system tested something needs fixed...

No. The only reason for putting it on metal remote from the battery is the fear that the battery will give off explosive hydrogen gas and the spark of connection will explode it. Touching it to the chassis is safer but electrically it is the same connecting location.

Always connect the + first, then the - to something metal on your engine block. If you connect to the - on your battery you can cause a spark and put yourself in danger. Keep your head away! Disconnect in the reverse order. (- then +)

You were misinformed. It's possible for the Battery to explode if you don't!
