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

FILE FILOSOPHY PREFACE TO EIGHTH EDITION In 1878, Mr. William T. Nicholson, founder of this Company, wrote and published a complete “Treatise on Files,” explaining therein the technicalities of files, defining their terms, and setting forth their uses, the processes of their manufacture, and the proper manner of handling them. This book has ever since been accepted universally as the authority in its line. File users have employed it as a practical guide in the art of filing, while mechanical experts and technical stu- dents have used it as a foundation for articles in the machinist and industrial press and for talks to the men in the workshop or class-room; it has even been supplied to other file manufacturers and its contents used by them in their catalogues and other publications. Whatever has been said or written upon the subject of files since the publication of that book has consisted simply of extracts or revisions of its contents. It has been circulated gratis throughout the world, and has passed through numerous editions. The last edition of the Treatise has recently be- come exhausted, and the book is now entirely out of print. To satisfy the continuing demand for a book of that nature, however, and in response to the urgent requests of innumerable of our friends, we have taken those portions of the Treatise that are of most imme- diate value and interest to the user, viz: the general description of files, their common applications, and hints on filing—compiled and brought them up to date and added only such matter as has in our opinion been NICHOLSON FILE CO.
