Let's see...
I have these on the same keychain: (Not to scale.) I've broken lots of flash drives, especially the bit which attaches them to the keychain, but this is sturdy enough to last 2 years and change with just a dent. The screwdrivers have lots of torque since the keychain can be used to turn them, good for breaking stubborn ones free.
And I carry this screwdriver for all the fancy torx bits which double as hex bits. At work it's the legend of the 'magic screwdriver' since it has all the funky bits needed to assemble a satellite dish horn or disassemble a hard drive. I've broken several over the years but kept all the best bits from each.
I also carry this for really high-power things. 3d-printed ratchet with reinforced metal bearings.
So if I'm ever trapped inside a locked bus, I can probably just attack the tempting screws and escape eventually.
