CHAPTER III 
CUTTING TOOLS 
5. Saws. The saw might be described as a succession 
of chisels, one back of the other. We can readily under- 
stand the action of the saw by making cuts with a nar- 
row chisel along the grain of a piece of wood, as shown 
in Fig. 10 at a. 
Fic. 10. Cutting with and across the Grain with a Narrow Chisel 
The little pieces of wood removed in this way are 
similar to the sawdust made by the saw, the only differ- 
ence being that in the saw the teeth are narrower and 
the little pieces consequently smaller, and instead of one 
chisel dozens are being pushed forward at one time. 
A saw with these chisel-shaped teeth, and used for 
cutting along the grain, is called a ripsaw.
