Can you tell me the name of the tool the video uses to tighten the bolt?

Some plumbers use a pipe-like tool they call a Basin Wrench, as it fits in the tight spot between the sink basin and the back wall. Tip: If the countertop is removable and the sink is light-weight, just flip the counter over and work on it upside down, then re-install.
