Remarkable.

My wife's grandfather passed away 40 years ago, I inherited his tools the 1139 Proto 3/4-7/8 wrench is still in use . The wrench is 50+ years old. I have twisted many wrenches of the same size in half, then reached for the Proto and got the job done. I am retiring in 2 years. And the wrench, we'll go home with me, and I will hand it down to my grandson. Thanks
