(MY way, hardly the only way) hand-carving should be learned and practiced before you get too involved with the power tools. Once you know what you want to get from a piece of wood, or metal, or whatever medium, you can learn to rough out your figure(s) with a Dremel and burs/files, and the settle in on the fine detail by hand. Most of the "set-up" is just removal of excess material, but to learn what, where and how much, to take off you must do it first with a blade. Like haircuts, it's hard to put some back. Many disdain the use of power tools as bastardizing the art, but I see nothing lost in cutting down the time on the "scut work". Many custom stockmakers use a pantograph to cut out blanks, using one of their own as a model. This is still art, as the finishing must be done by hand, and the original was theirs to begin with. There are those who disagree, but their stocks take months longer, and they are finding themselves priced out of the market. New stuff isn't bad unless it is misused.
