[Fig. 9] is the end of a thin-edged, flat scraper, and is chiefly to be used on brass work. It may be of any length and size, but for small lathes, and light work, it is cheaper and handier to make it of thin sheet steel, one eighth or one tenth of an inch thick, and to form the reverse end into a round nose, or half-circle scraper.

It often happens that fillets or hollows occur, as in finishing ornamental brass work, in connection with flat surfaces. By having such a tool as this, the necessity of laying one tool down and picking up another, is obviated, for the two are combined in one. For iron work, it is customary to use a heavier and thicker tool for finishing. As in Fig. 10, the front edge is slightly raised or concave, to make it sharp and hold a cut well. All turning tools for finishing iron are made thicker than those for brass, and should have lips, or curved cutting edges. Such tools cannot be used for brass, as they are too sharp; the edges jump into the metal and spoil the work.
A tool for scraping brass work of some kinds is made as shown in Figs. 11 and 12.

There is no occasion to make the ends at different angles, except the convenience, before stated, of having four cutting edges on one piece, for any angle can be easily given by the position of the hand or the direction of the rest. These tools, here alluded to, are only to be used when the job has been all turned true and the scale removed; they scrape, merely, they do not cut.
