The first one was clever, the last two were unneccesary...

I’d say under engineered for the last two because they are too complex.

The first one might be well engineered for a person that opens bottles all day long.

IMHO, good engineering means simple & reliable while meeting the needs of the user.

The third one is just plain ludicrous.

For opening jars, (as opposed to bottles) I've always used a very old design that works very well...


It's a nice simple, clean design and, being all metal, won't break easily. Fits any reasonably sized jar and even my wife can use it with arthritis weakened hands.

We use a board with a 90° V cut in the face. One side of the V has a hacksaw blade. The board is fixed to the underside of a cabinet. Lift a jar into the V and twist off the lid. Amazon sells them. Not as portable as handheld but both hands are free to hold the jar.

I made this one from a piece of scrap white oak and a piece of thin angle. I hook the curve around the cap and push down on the opposite end. It removes the cap without distorting it. I use the caps to make beer clocks.

This one is spray painted with faux stone paint. I make a different style with red oak sprayed with polyurethane. I gave my daughter my last one of those, so I don't have one to present here.
