Wow, that's terrible.
I can't image ever using one of the wrenches. For one thing, they're all smaller sizes, and then the other thing is because the of the shape of the tread, you'll be pretty limited in what you can actually apply them to.
And the same goes for the bits, it's rare that I need any of those sizes of bits, and when I do, I'm probably going to need a longer shaft than the design allows.
Oh, an recently, I tried using on of the bits for my leatherman without the tool, because the handle was too bulky for what I needed, it was difficult to turn the rectangular shape, those screwdrivers are going to be a pain to use. You'll probably only be able to make a 1/4 turn effectively. I'm surprised this ting made it off the drawing board.
This thing is pretty much a failure from a practical standpoint, and as far as fashion, with all of those screw heads linking everything together, forget about it.
