CHAPTER IV 
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 
Fic. 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 4. 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.
