Seriously, this book is so awesome, it caused Adam Savage (yes, the Adam Savage from Mythbusters) to joyfully exclaim, "It's got everything in it.... It should be in everyone's toolbox." We'll let that quote speak for itself.

Do you stay up at night pondering what kind of electrical plugs they use in Western Ethiopia? Are your semaphore skills a little rusty? And just how the heck do you tie a Crabber’s Eye Knot, anyway?

If these and other such questions occupy your waking thoughts, then this is the book for you. The Pocket Ref, 4th edition really does seem to be the Holy Grail of information. It is small, yes, but loaded with facts, figures, tables, and illustrations of almost any subject you can imagine. Get a copy of this book and you’ll never lack the answer to life’s nagging questions again.
