t. Thus in splittingwood the cutting-edge starts the cut, but soonceases to work, as the wedge-shaped blade splitsthe wood in advance (Fig. 370). The more acutethe cutting-edge the easier it will work, providedit is obtuse enough to give the necessary strengthto the end of the tool. Soft wood is more easilybent aside or compressed than hard wood so thatthe angle can be more acute for the former thanfor the latter. Thus, to always cut to the bestadvantage, the angle of the cutting-edge should,theoretically, be changed with every new operation, but all that can bedone practically is to have a longer bevel for soft wood than for hard. Saw-filing is hard for beginners to do well, and it is soon enoughto undertake it when the pupil has become quite familiar with the use oftools, for it does not need to be done very often and costs but little. Thesaw-filer should know for what work the saw is to be used and whether forhard or for soft wood. It is easy to understand the theory of setting and

The teeth are first jointed, or reduced to the same level, by lightlypassing the flat side of a file over their points, lengthways of the saw. Thesaw is firmly fastened in a saw-clamp, so that it will not shake or rattle.At a north window is the best place for the clamp, on account of the light.The teeth are set by bending them outward, one tooth toward one sideand the next toward the other side. Do this with a saw-set. A toothshould not be bent for more than half its length. For a cross-cutting saw the file (a triangular saw-file) is held at an anglewith the blade depending upon the particular form of tooth adopted, aswill be seen by examination. Hold the handle of the file in the right handand the point between the thumb and forefinger of the left hand (Fig. 371).Push the file across with an even, straight stroke, without a
