Also, I remember seeing a YouTube of someone rigging up a paperclip for heating all the pins at once.

The trace amount of solder left after desoldering is sometimes called a "sweat joint". It can be broken by rotating the pin, which works fine for round through-hole leads but not so much for flat SMT leads. Paul is right, the fancy tool would be either a hot air tool with an appropriate nozzle or a U-shaped soldering iron tip for heating up all the pins at once. Again, the tip is sized for the chip.

Ah, yes, making a soldering iron from a paperclip taped to a lighter.

The desire here is to minimize the amount of heat injected into the PCB. In this case, since you're not trying to salvage the chip, the X-Acto method is an acceptable choice.
