The Solder Vacuum, a great (and sometimes underappreciated) little tool for solder rework. It allows you to pull the molten solder out of a connection or via with ease.

To use it you simply:

1. Depress the plunger
2. Heat up your solder,
3. Place the nozzle over the solder you want to remove
4. Push the button.

The piston pops up and the solder disappears! This solder vacuum has a black metal body with a hard plastic nozzle and buttons.
