MISCELLANEOUS TOOLS AND METHODS OF WORK 



18. Hammer. The carpenter's hammer is used prin- 

 cipally to drive or withdraw nails. 



The various trades have hammers made specially for 

 their needs; thus we have machinists', roofers', up- 

 holsterers', stonecutters', and other ham- 

 mers, but the claw hammer shown in the 



FIG. 42. The Claw Hammer 



sketch is the one commonly used by work- 

 ers in wood. 



The head a (Fig. 43) is of steel, with the face b spe- 

 cially hardened so that it may not be dented by the nails. 

 Notice the length of the handle h. This length did 

 not simply happen. Had it been intended to hold the 

 tool in the position shown at A, the handle would not 

 have been made so long. The proper position is that 

 shown at B. Position A is frequently taken by begin- 

 ners, and should be studiously avoided.
