Hmm maybe he'd better order a bunch of them then.Keep it in your glovebox... nothing breaks a window better. My wife keeps one after watching a news thing about a submerged car. In her defense, we were in Montana and the road to town had a sweeping left curve with the river to the right. They pulled more than a couple of cars out of the river there.
They will take out automotive glass faster that anything else; and you don't have to swing it like those hammer things they advertise.
I was working up here (Seattle) when I got it, along with $20K in other Snap-On stuff (and that was 1977 money); I still have all of it, and then some that I acquired over the years. I probably have $180K worth of tools out in the shop. I bought so much Snap-On stuff in the late 70's and all through the 80's they gave me the Snap-On embroidered jacket (yes, I still have that too but it's a tight fit).Coss, if yours is 35 years old, there's at least a chance that I handled it in the warehouse.
