I. Read and translate the text Hand Tools
In all professions and trades the beginner must first acquaint himself with the various tools he will meet and must also learn their different forms and uses. The working place of the tradesman is a specially designed table with vice and drawing boxes to keep tools. The vice is secured to the table and is used to hold an object in position.
To these tools belong: hammers, chisels, pliers, files, spanners, screwdrivers, various marking and measuring tools, etc. Hammers are classed as hand hammers, sledgehammers and special hammers.
The hammer consists of a head, which is fitted to a wooden handle. The length of a handle depends on the weight of the hammer. Pliers are used for gripping or holding small objects by manual operation. The most common type is the plain type of the pliers. Spanners are used for tightening up or unscrewing of nuts and bolts. There are two types of open-jaw spanners: the single-ended and the double-ended.
