Boggs Spokeshaves
If you're working on a woodworking project that isn't of the typical square/rectangular form, then the Lie-Nielsen spokeshave is going to be your new best friend. There are three versions of this spokeshave (Flat, Curved, and Concave), and in this article, Lee Laird discusses the design, sharpening techniques, and use of the Boggs Flat Spokeshave. He includes information on different jigs you can set-up to assist with sharpening the irons, as well as the adjustments that can be made to the irons so they can make the best cuts.
