I remember first seeing The Boa Constrictor Strap Wrench on television. It was love at first sight. I knew that it would work beautifully on all those hard to open jars and bottles.
It works so well, that I put the larger one into the car for just in case.
For those stubborn jars, I’ll use the Mightigrip Jar Opener on the lid and the “Boa” to hold the base of the jar steady.
