Added Res-Q-Me's to my truck key chain and also my wife's. Also have a Lifehammer in the console of my truck.

I got a three-pak of blue Res-Q-Mes from amazon.com, so I have one extra. I was thinking of putting it on my tractor key chain. No window, but I wear the lap belt as part of the rollover protection system, and if the tractor were to roll and I was hanging I could see where the buckle should get stuck and I might need to slice the lap belt to get out.

I could also use it to open envelopes while mowing ... just kidding. Of course the blade should be preserved for its intended purpose.
