Side-Jointing. Usually, when the filing is finished, the saw is ready for use, but it will cut more smoothly if it is jointed on the sides of the teeth. In Fig. 83, B is side-jointed, the surfaces produced agreeing with the dotted lines; A is not side-jointed.

Side-jointing may be accomplished by use of either a file or an oilstone. It is always necessary after a swedge set has been used.
