I have almost all my grand dads tools even though I never met him. He built his own house with those tools and when my grandmother passed we clean out the cellar. Most were passes up by my family. I still use them on occasion today but I will say the dewalt is an awesome product. I have drill impact wrench and sawzall. 18 volt still running strong.
I have a sawzall, we keep in the shed for semi emergencies.
It and my DeWalt tools added about 5 years to our Redwood deck. It will be finally replaced in a few weeks.
