cornered file, the latter preferred for split 

 bamboo work. Also get a sheet of fine emery 

 cloth; coarse, medium, and fine sandpaper; a 

 small, thin saw; a flat steel scraper. A drill 

 stock and several small drills are always use- 

 ful. 



Calipers of some sort are necessary. The 

 best obtainable is the micrometer caliper reg- 

 istering thousandths of an inch, with scales 

 showing equivalents in 8ths, i6ths, 32ds, and 

 64ths. One of these costs about $4, but its 

 graduations are so fine that it is useful in other 

 work as well as in rodmaking, and is almost 

 indispensable for the angler who wishes to ob- 

 tain exact calibers of rods, lines, silkworm gut, 

 etc. These calipers are made by several firms, 

 and all are of the form illustrated in Fig. 25.
