Hot side tools that make you're life easier?

Like the title says. I'm on week 2 at my job still going through training for the next month in a half. I have all my refrigeration hand tools (I'm sure I'll never be done buying them). I'm just wondering what hand tools make life easier other than wrenches, pipe wrenches, screwdrivers, ect.? Like my trainer says a tech is only as good as his tools.
