You can buy a 6-inch Crescent-type wrench for as little as a couple of dollars, or your can spend up to $8 for one that, at first glance, looks identical. In this case, however, the "bargain" is no bargain. To be reliable, a wrench must be made from the finest chrome-vanadium steel. One way to judge the quality of a wrench is by weight-- the cheap ones are heavier because they are thicker. This is an attempt to make up in quantity of metal what they lack in quality. If you buy a cheap wrench, it may work all right for a while, but with time and use, the jaws will bend so that they are no longer parallel. Once this happens, the wrench will never fit anything properly -- you will have to throw it away and buy another.

If you buy a good-quality wrench, it should last indefinitely. The better brands come with a lifetime guarantee. In particular, the Craftsman line from Sears Roebuck and the Blue Point from Snap-on have a lifetime guarantee that is good anywhere in the United States. If you have a broken Craftsman hand tool, you can take it to any Sears store for a free, no-hassle replacement.

The same is true of Snap-on, except that Snap-on has no regular retail stores. Snap-on tools are sold out of big white vans that are rolling tool shops. These vans have regular routes, primarily selling to garages. If you are riding by and see one of these trucks parked, stop and talk to the driver, who will be glad to give you a catalog and sell you any tools you want.

Snap-on tools are very expensive, but they are also the very best. The Snap-on Blue Point 6-inch adjustable wrench is the lightest I know of, weighing 100 grams, compared with 125 grams for the average good-quality unit. It also opens wider than most.
