[Grumpy old man]

I've been building my tools for over 40 years and always looking for the next specialty tool ,but it's also good to have a box of sacrificial wrenches that can be heated and bent to fit what your working on rather than tear up your good stuff . I can't tell you how many times I've used a electric 1/2" impact with the power inverter to change tires on trailers or that next project with flat tires found in a barn .
