Open tight jar lids
I have used the UN-SKRU under-cabinet jar opener since 1979. It allows you to use two hands to open jars and bottles and it works very well.
The lid is jammed between a knurled steel post and a logarithmic spiral step which in effect automatically adjusts for different size lids. My wife really appreciates the ability to grip a large jar with two hands when opening it.08/31/15
