Spokeshaves, and cabinet scrapers, are used to form objects and carve wood. I used mine to take a 2x2x3 piece of wood and carved it into a shaft for my bench vice. From the name you can identify one use the tool has. People used them to make spokes for wagon wheels. Baseball bats can be made from a spokeshave too.

They are very easy to use and offer a great deal of control you cannot get with a plane or chisel.
