For The Function

A carpenter might use his hammer to drive a nail into a board, but he gives little regard to the tool beyond the fact that it functions to perform the task at hand. The simple relation between form and function. As items or tools grow more complex, the concept of tolerance is applied. After all, what good is a tool/item if it does not produce the same result time after time?

Then we arrive at the items on this list. Having met tolerances and been found to be useful, they have gone further - they have met the challenge with style. See if you don't agree.
