Small pieces of steel, MAKING CHASING TOOLS. 29 roughly forged into shape, and called brindles, are manu-factured and sold for the purpose.

Ofcourse, it must be held during this operation with a pair ofsmall tongs or pliers; being small, it soon cools, and may. Fig. 20. Square. have to be heated again. Having got it roughly into shape,he then either grinds or files it until it is exactly the shaj>erequired. It is then rubbed up on the oil-stone, until all thefile marks are removed.
