I just lightly tap the lid with a knife around all edges, side and top. Even if making small indentations, the vibrations separate the lid from the jar. Works every time.
Yes, that does work. It’s not the vibration, the dents change the contact surface pressure of the seal by making it uneven. That makes less surface to fight against.
I was trying to offer an alternative to something that might chip or break glass. Small odds that it will happen, but it could. I’ve probably only ever had 2 jars chip in a lifetime.
