In lumber, rough sawn or planed, wane or "waney edge" is where bark -- or other disfigurement -- from the original tree remains. Wane is where, on a board, the Natural Edge of the tree tapers, leaving a bark-covered area on a board's surface, usually its edge (see image). In most cases, a wane in lumber creates an issue that woodworkers seek to correct, by -- and there are several strategies -- cutting the disfigurement out. In other cases, where, say, a woodworker is seeking a decorative Natural Edge look, the wane is incorporated into the project.
Below is a section adapted from the Oxford English Dictionary showing, historically, examples of the use of wane as a term as it is encountered in the process of turning timber into lumber:
The amount by which a plank (esp. one sawn from an unsquared trunk), or a roughly squared log, falls short of a correctly squared shape. Hence the bevelled edge left on a plank (by reason of one face being narrower than the other), or the imperfect angles of a rough-hewn log.
