Cheaper and probably even easier than Rolands contraption (some olives are oddly shaped, and the de-pitt-ers tend to prefer round things), is taking a broad, solid knife and giving the olives a good whack with the flat of it.
You put the olive under the knife, set the knife down on the olive so its stable, and tap it with the heel of your hand. Blows the olive open and you can pull the pit out easily.
