In sixth grade, I was given a Victorinox Swiss Army knife. I loved it. An avid camper and erstwhile Boy Scout, I was amazed at how many things I could do with this well-made, pocket-size wonder. I used its tweezers to remove splinters and ticks, its scissors to cut thread, its can opener to prize open tins of baked beans, and its knife blade to whittle, occasionally cut myself, and generally wreak teenage mayhem.

As I grew older, I discovered that using specialized tools for a given job was generally easier, faster, and more pleasurable than using my Swiss Army knife's utilities. Though I could cut a tent's ground cloth with my knife's scissors, a plain-Jane pair of Fiskars worked much better, an OXO can opener got me into those baked beans much faster than my Victorinox could, and even my Swiss Army knife blade didn't stay as sharp or fit in my hand as well as a simple Buck knife. Still, there was no doubt that my Swiss Army knife was a great tool and a good value, even if it was never the best tool for a specific task. To put it another way: The value of my Swiss Army knife was broad but shallow, while the value of something like my OXO can opener was narrow but deep.

The English public may not like music, but they absolutely love the sound it makes.—Sir Thomas Beecham

Just as car magazines are filled with descriptions of how fast their subjects don't go and how surely they don't stop, magazines such as ours are filled with descriptions of how neutrally our subjects don't play tones, and how precisely they don't place images in space.
