File Filosophy
Being some Hints regarding the proper Methods of using Files and the various Applications of the most common Files

FILE FILOSOPHY USES OF FILES The More Common Files Briefly Described and Their Uses Stated On this subject it will be our purpose simply to name in so many words the distinguishing characteristics of the more common files and very briefly to state the or- dinary uses to which they are applied, with a view to aid the reader in making the proper selection of a file for the work which he has in hand. Our catalogue illustrates all the more generally used files, but the following chapter, in describing the shape and specify- ing the ordinary lengths, complements the illustrations in the catalogue; at the same time, by showing the section and describing the cut, it does away with the necessity, though not the desirability, of reference to the catalogue. For the sake of simplicity, we have pursued a regular order throughout our descriptions. First, treating the files collectively, we classify them according to their cross sections, as explained below, under the heads of quadrangular, circular, triangular and miscellaneous Sections. Then treating each individual file, the Cross Section is shown; we next specify the Shape or out- line of the file, as Blunt or Taper; then follows the character of the teeth, as Single, Double or Rasp Cut*, we next name the degree of coarseness of the teeth, as Bastard Cut, Second Cut, etc.; and last the length in which the file is more generally found is given.
