A set is put on a blade before mounting. This set brings the tip of the blade more centrally towards the target when you are standing en garde. This is done by placing the tang of the blade in a vise and pulling gently on the forte (the thicker end of the blade just above the tang) of the blade. A set should be down and to the left for a right handed fencer; down and to the right for a left handed fencer. The set shown here is a standard set of about 7-9 degrees; a heavy set is bent more, a light set is less.
