I am gonna go on record saying that the single most versatile tool in my box is the Veritas spokeshave from Lee Valley Tools. Not cheap, but you get a choice of tool steels (A2 and O1) for the blade and it comes viciously sharp. The body is of a higher grade cast iron steel, and does not shatter like the cheap versions from other sources. When properly sharpened, it rarely tears out grain unless you are in swirling grain around a knot.
The bed for the blade is machined dead flat, so the blade is fixed in place with only a little pressure. Cheapies like Stanley/etc are anything but flat and you need to crank it tight to keep the blade from slipping around. A well bedded blade also does not chatter as much.
Most people seem to put the blades in UPSIDE DOWN! Bevel down gives you a much sharper cutting angle and parts hard and soft woods much nicer.
I'll set my blade deep and use my forearms to keep the tool wedded to the stave to hog off thick shavings, but I can also fine tune it down to split cigarette papers three ways, too.
Like any tool, you have to learn how it operates and how to make best use of it. You cannot go at it like John Belushi, Samurai bowyer, in the throes of a cocaine fueled epileptic fit and expect decent results. Granted, it is a poor workman that blames the tool, but you notice they do not build high tech communications satellites with a selection of rocks and a bent screwdriver, either.
