I have been using a Park Took SW-40 for maintaining the wheels of the family's "good" bikes for several years now. So when my four-year-old son got a Wal-Mart Mongoose child's bike for Christmas, I immediately got the SW-42 based on my experience with the SW-40, and on my experience with Park Tools in general.
The SW-42 (or SW-2) is the size required by the spoke nipples on common "department store" bikes, like those produced by Pacific Cycles. If your bike did not come from a dedicated bicycle shop, this is probably the size your bike will require.
There's not much more to say about the tool. It is durable, it works, and the rubber coating makes it very nice to work with for long periods of time. The tool is very reasonably priced, and leaves little reason not to get one in each size that you require.
Just a note in case you were wondering. The Park Tool SW-0, -1, and -2 only has two corners and three sides to the wrench. The SW-40, -41, and -42...
After buying a crap-tastic second rate all in one tool to keep my bike in order, I spent most of my time tearing up spokes and never getting anything tight enough to stay. My friend that had just recently sold off his bike repair/retail shop suggested I try this to keep my adjust my spokes accordingly. This thing is amazing. I bought both the red and black version as my front tire has smaller spokes than my bike tire. These are incredible. You could tighten a spoke so tight to snap it with very little effort. They do exactly what they are supposed to and are small enough to fit in a small pocket. If you need a spoke wrench CHOOSE THESE.
The idea behind this is that it provides a better grip on a spoke nipple's 4 flat sides than does a wrench that encompasses only 3 of them. It accomplishes this task, but not as completely as you might imagine. It does this by having two small additional right angles that wrap around (barely) the 4th side, at the opening that would otherwise form a 3-sided 'C'. The legs of these added angles are very small -- almost imperceptible to my aging naked eye -- but they're there. And they do help.
One thing to note is that, if your spoke nipple is already rounded off by using a conventional 3-sided wrench, you may have trouble fitting this tool on the nipple. Replacing the nipple is the solution to this, but if you're just making a minor truing adjustment with the tire on the wheel, that can be inconvenient.
Is this wrench worth a couple of extra bucks over the cost of a conventional 3-sided wrench? I think so, especially if you're purchasing your first spoke wrench...
