Mechanic's Tools and Their Makers

  How to Sharpen by Behr-Manning, division of Norton Co., 1955    

A book for the home craftsman, farmer, mechanic, and others who use edged tools.

The most profitable single investment in any field of tool handling, from pocket-knife whittling to the most exquisitely fitted cabinet work, is the time and effort needed to provide and maintain keen edges on cutting tools.

Many craftsmen - amateurs and others - using for the first time really sharp cutting tools, have discovered in themselves unexpected capabilities for accuracy and nicety in their work, as well as vastly increased gratification in the doing of it.

Unfortunately, surprisingly many tool users have never known the pleasure of using really keen-edged tools, and thus toil with half-dull tools to achieve mediocre results.

Others feel that a truly keen edge is beyond their ability to produce, or are unwilling to give the long time and great effort they erroneously believe it requires.


Contrary to these beliefs, a truly sharp edge can be obtained by almost anyone, with little or no more time and effort than a rough, imperfect edge.

The purpose of this book is to detail the methods and equipment used by experts, which will enable any man to obtain an edge as keen as the steel of the tool will hold - and to do this so quickly and easily that he will never again be content with anything less than the sharpest of edges, and the quality of workmanship which only fine edges can produce.

Let's take a typical edge as on a plane blade or chisel. By magnifying it greatly, we can see what it looks like when dull, and what happens to it in the stages of sharpening.

The edge, as shown in Figure 1, is magnified 20 times. While it could still be used, this edge would really tear rather than cut.

The cutting edge has broken down or worn off. Further, it is also chipped by accident or impact against a hard knot or other substance.

An edge like this would never be tolerated by the professional craftsman, but it is safe to say that it may be found in some home workshops.
