What Did You Do With Your Truck Today ?

[Russell Ashley]

I like old tools and that lug wrench looks interesting to me. It's actually called a Shock wrench. Here's a link to a tool vendor that gives a little info about it. I first assumed that you hit the ends with a hammer to loosen the lugs but you just spin the arm and the weight of the ends acts like an impact wrench.
