Back in the 70's I was with my dad in his pickup when he got a flat rear tire. We found that the front had kicked up a 7/16" Craftsman combination wrench that had landed just so that it penetrated the rear. The wrench was scarred up but serviceable, so dad kept it. Then about 10 years ago I came across that wrench in the tool box under the passenger seat of his CJ5. The jeep had sat for many years, the top rotting away, nothing to keep the rain out. Everything in the underseat tool box was a rusted mess, but I recognized the wrench from the gouges out of it. It was so rusty that the size could hardly be read but "Craftsman" was legible. One say I was going to Sears and took it along as a joke, saying the wrench was defective. Without batting an eye, the salesman offered me a new one. I said that was above and beyond the call, but he said no problem. I took him up on it, though later I wished I'd kept the wrench as a momento. I'll never forget my dad's reaction when we found that dang wrench imbedded in the almost new 8 ply tire. As you might imagine, it ruined the tire.
