Adze

An adze ( /ˈædz/; alternate spelling: adz) is a tool used for smoothing or carving rough-cut wood in hand woodworking. Generally, the user stands astride a board or log and swings the adze downwards towards his feet, chipping off pieces of wood, moving backwards as they go and leaving a relatively smooth surface behind. Adzes are most often used for squaring up logs, or for hollowing out timber.
