So you have to do something simple, like tighten a doorknob handle. This SHOULD be a quick task. Unfortunately for you, your screwdriver is in your tool kit which is buried somewhere incredibly inconvienient because you do not have a garage to neatly store these types of things in.
Fast-forward to you digging the tool kit out from the never-ending abyss that is the cabinet underneath your kitchen sink. It doesn't have to be this way.
The GENIUSES over at Strelka came up with ToolBook ($129, Strelka), a tool kit housed within a book that can be easily slipped into your bookcase for easy access.
The ToolBook contains 4 types of screwdrivers and 6 types of wrenches. You'll never be shoving your head under your kitchen sink, grappling in the dark for a tool kit when you just want to accomplish a simple task EVER again (except, I guess, when you're trying to find your hammer).
