Sharpen the corner into a screw driver shape..it will get some
screws
tight/loose. Sharpen the other corner into a blade..it will skin a
rabbit. Messy...but it works

I've carried a $5 copy of the Swiss Army Knife for decades:

The small screwdriver on the tip of the can opener works on #2
Phillips if they aren't too tight. The tapered point is a drill bit
that makes starting holes for wood screws. Sulphuric acid doesn't
attack the stainless steel flat blade after it pops the vent caps off
a battery.

The can opener may be slower than the video showed but the knife is
easier to carry than a chunk of concrete.
