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

FILE FILOSOPHY as to bring the thumb, as its ball presses upon the top of the file, in a line with the handle when heavy strokes are required. When a light stroke is wanted, and the pressure demanded becomes less, the thumb and fingers may change their direction until the thumb lies at a right angle, or nearly so, with the length of the file; the positions changing more or less, as may be needed to increase the downward pressure. In holding the file with one hand, as is often necessary in filing light work, pins, etc., the handle should be grasped as already described, with the exception that the hand should be turned a quarter turn bringing the forefinger on top and lying along the handle nearly in the direction of its length. In this position, the freest action of the hand and wrist may be had upon light work. Amateurs will find that by following these direc- tions, the movements of the file will be simplified and made somewhat easier than if grasped at random and without consideration. Carrying the File The most natural movement of the hands and arms in filing is to carry the file in circular lines, the sev- eral joints of the limbs being the centres of motion; this movement of a convex file would apparently give a concavity to the work, but the real tendency, especially on narrow work, is the reverse, owing to the work acting as a fulcrum over which the file moves NICHOLSON FILE CO. 19
