Design and Use of Cutting Tools (1952) Book Leo J. St. Clair This is the definitive source for sharpening metal lathe tools, especially carbide ones. St. Clair was working in the industry as it was changing from HSS to carbide, so both are covered well. His experimental data helps validate or disprove many theories.

Unfortunately, this book is very hard to find. I recommend the sharpener borrow it from their local library via an inter-library loan for reading. Universities which teach mechanical engineering usually have a copy, and it is easiest to read that way. (The publisher has no more copies : I asked.)

Knife Deburring: Science behind the lasting razor edge Book Dr. Vadim Kraichuk Dr. Kraichuk's book is based on the sharpening method developed by his company. And unlike other sharpeners, Dr. Kraichuk has researched the results from using this method, and has proof that it works. His company's work, sharpening the knives of butchers, has repeatedly shown that his method is sound.

The site's focus is on usage of electron microscopy (EM) to physically observe the geometry and polish of the edge, and to quantify the edge width and bevel angle.

The EM scans and experimental data helps validate or disprove many theories.
