We recently found out about the Screwpop 4-in-1 keychain tool, which offers a bottle opener, #2 Phillips screwdriver bit, flathead screwdriver bit, and a 1/4″ nut driver in a tidy key-sized package. If you consider that the flathead bit can be used as an impromptu pry bar, then the Screwpop is in fact a 5-in-1 tool.
We are slightly concerned about what would happen if the reversible screwdriver bit were lost, but if the friction fit ball bearing is secure enough (and it looks like it is), this shouldn’t be an issue.
While the Screwpop may not be an ideal screwdriver, it is unobtrusive and very easy to carry. Just slip it onto your keyring, and you will probably forget all about it until you need to use it. It is safe to say that it is far better to carry something like the Screwpop than nothing at all should the need arise.
Screwpops can be purchased for $4.95 each plus tax and shipping. Shipping to our location came out to be $3.50, and you can ship up to 5 Screwpops at the same rate. A bin of 200 Screwpops to resell (or dispense to friends, family, and coworkers) will set you back $200 plus tax and shipping.
