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. 



FIG. 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.
