Introduction to Woodcarving: Whittling

You probably know what woodcarving is. It's simple. Generally, you take one sharp object, put it against some wood, and push. Now you know how to carve anything in the world. (I'm oversimplifying, but you get my point.) But if you're here, and I really don't know how else you would be reading this, then you might be interested in learning about the esoteric differences in how to push (or dare I suggest pull.) that sharp object across that wood.
