CHAPTER I 
INTRODUCTION 
In order to obtain good results in the using of tools 
it is necessary to know their construction, how to prop- 
erly sharpen and adjust them, and the correct method 
of handling them. It is also essential to know how to 
lay out and work the material or stock. Carelessness 
or a lack of knowledge is invariably followed by a 
failure. It is more important at first to work carefully 
and accurately than rapidly. 
“Tools are made to be used, not abused.” They 
must be kept clean and sharp and should be used only 
for the purpose intended. Wipe them off occasionally 
with an oily rag or waste to prevent them from rusting. 
Put away all tools not in use and keep the top of the 
bench clean. Do not mark it with a pencil or scratch 
it with a knife. Do not cut into it with the chisel 
or allow other tools to mark or deface it. When using 
glue, shellac, or similar materials, cover the top of the 
bench ; or, better still, do the work on a table provided 
for that purpose.
