What are some lesser known items or tricks in your profession that most people don’t know about?

For me one thing would be Thrift drain cleaner. I was having issues with my drains being clogged and nothing really worked, but looking around on forums and advice from plumbers lead me to Thrift and now my drains work great.

    Not to partially side with the other guy but I have indeed gotten sets with a 6.3mm, or at least labelled as that, socket. The elusive 12.7 remains to be found.

      This is interesting! Is it an imperial socket labeled in metric? Is it a specialty socket?
