Took the P-38 off my key chain years ago when the thing somehow managed to gouge me while I was climbing a tree.. It was very old and worn and wouldn't stay closed any more.
You can put a safety pin through the hinge to keep the P-38 closed.
There are entire sites dedicated to everyday carry (EDC) with some sites focused on flashlights, knives, Atwood tools, etc. You can spend a lot of time and money on EDC "research"

Why do ISPs still provide email? There are lots of free and pay for email servers available. I say reduce my bill $1/year and get rid of it.

So why don't they just use their formula to compute the last digit of Pi already? That would be the rational approach. Who cares about the two quadrillionth digit??
If trailing zeros after a decimal point (e.g., 3.500 = 3.5) are not significant digits, then I believe the last digit of pi in binary notation have to be 1.
Therefore, pi = 11.00100100
