I ran across this cartoon: [Link]
It reminds me that the most valuable (personally) item in my bathroom cabinet is a flush cutter. For those who are not tool savvy (a few bogs are and a lot of geeks and nerds aren’t; go figure;) a flush cutter is a wire cutter with a single edge. The outside of the cutter blades are unedged so it cuts the thing being cut evenly. So far I have not encountered a child-proof (actually adult-proof) top that cannot be defeated.
In some cases the answer is to cut on the cap or top; in other the flanges on the bottle/container. But it works and I can triumph over the tyranny of drugstores, politicians, and manufacturers.
At least in this regard.
Not good for trimming nasal hair.
