For Cross-cutting.—For ordinary cross-cutting the angle of the saw should be at 45 degrees. For ripping, the best results are found at less than 45 degrees, but you should avoid flattening down the angle. An incorrect as well as a correct angle are shown in Figs. 21 and 22.
Forcing a Saw.—Forcing a saw through the wood means a crooked kerf. The more nearly the saw is held at right angles to a board, the greater is the force which must be applied to it by the hand to cause it to bite into the wood; and, on the other hand, if the saw is laid down too far, as shown in the incorrect way, it is a very difficult matter to follow the working line. Furthermore, it is a hard matter to control the saw so that it will cut squarely along the board, particularly when ripping. The eye must be the only guide in the disposition of the saw. Some boys make the saw run in one direction, and others cause it to lean the opposite way. After you have had some experience and know which way you lean, correct your habits by disposing the saw in the opposite direction.

The Stroke.—Make a long stroke, using the full blade of the saw. Don't acquire the "jerky" style of sawing. If the handle is held loosely, and the saw is at the proper angle, the weight of the saw, together with the placement of the handle on the saw blade, will be found sufficient to make the requisite cut at each stroke.
You will notice that the handle of every saw is mounted nearest the back edge. (See Fig. 23.) The reason for so mounting it is, that as the cutting stroke is downward, the line of thrust is above the tooth line, and as this line is at an angle to the line of thrust, the tendency is to cause the saw teeth to dig into the wood.
