I have the Holy Grail.....
The cast iron Connecting Rod Bottle Opener from GM Research.
My father retired from GM Research Labs in Warren MI. They gave these away at their 1976 Open House.
I grew up with that Conn Rod opener always in my Mothers kitchen drawer.
For my career, I spent 20+ years designing engines for Ford. Engines and cars are my passion. I always wanted that opener, but it was lost for years.
After my father passed away, I found this cleaning his tool box. I swear it glowed in my hands when I picked it up.
I think of my Dad almost every time I open a beer.
I will always keep it and use it regularly....
I highly doubt I ever see another like it....
