Plates from the microwave? Yea that would be pretty annoying actually those are hard to find.
What about, if you could steal the blades off of ANY sharp object, leaving the rest behind.
Useless knifes, no razors, can't mow your lawn, can't cut your hair, can't garden, can't use blender. And depending on what you consider to be a blade, just remove any and all sharp objects from existence lol.
