(1) A tool with a sharp blade and a handle at each end. It is used to strip bark from small-diameter logs, and looks a little bit like a set of bicycle handlebars.
(2) A carpenter's tool. It is a thick bar of beveled steel sharpened like a chisel on one edge. The blade has a wooden handle on either end, attached at a right angle to it. The blade is used by pulling it along a piece of wood toward the user's body. This shaves or planes off a strip of wood. The amount removed in each stroke depends on the angle of the knife and the force applied. This tool is used for removing bark and for rough shaping of the wood.

(2) Drawknife. A tool once common among 18th and 19th century (and earlier) carpenters, wheelwrights, and house builders. Still used by trail crews.
