I bought a piece of 1.5 inch stiff foam to try to fix a sag in a bed. It didn’t work but having that thick piece of solid foam around has been a life saver.
Need something flat to put a laptop on? Throw it on the foam. Going to be doing something that requires you to be on your knees for a while? Get the foam!
It went from stupid purchase to something I’d gladly replace if it broke.
If you get good butter knives instead of cheap ones, you can open lots of things without ruining them. I use a butter knife to separate frozen hot dogs and can’t tell which ones were used for that after they get washed and mixed back in with the others.
Unless you’re talking about the tape residue. Yeah, I use a pocket knife for that. Mine has a curved blade so I can imagine I’m a velociraptor while opening boxes.
