This may be the best tool purchase I've ever made in my life.
I had been searching for easier ways to pull off broken or otherwise stuck car fasteners. I've used cheap metal and plastic pry-bar like solutions that came with fastener kits. They either were entirely inadequate or ended up scratching the interior surfaces where pressure was being applied. These tools make life 100x easier and make pulling out car fasteners simple, effective, and with minimal effort.
