Are there any household gadgets you found unexpectedly useful after you'd gotten them?
I was thinking about how I missed having an indoor thermometer that measures humidity. It's such a small specific thing, one I'd never think of getting unless pushed to it (which I was by one particularly dry winter). But I like having one now.
What are your small, "random" or "junk drawer" type of gadgets that you actually use or like having around?
I find a butter knife has a similar effect as the first tool you linked. Jam it into where the lid meets the jar and then twist and/or pry to pop the seal. It's been the quickest and easiest way to open these kinds of jars for me.
I've seen other people just smacking the lid with a knife for some reason and I have no idea what that is supposed to accomplish lol. Doesn't work that way.
For a jar opener, go right past the kitchen aisle or page and into hardware. Get a rubber and plastic strap wrench. if you get the two pack, keep the big one int he garage and the smaller one in the kitchen.
