What are your favorite and most helpful tools?

I picked up an Ingersoll Rand 20v impact wrench. It’s rated at 780ft-lbs. of torque. This thing is awesome and I don’t know why I didn’t buy one a long time ago. It saves so much time and just makes things generally easier to do.

Now I just need to get used to all the torque.
