Lesson 3: How To Thin A Knife

Learn how to thin a knife with Jon Broida in this 3rd lesson of the Free Knife Sharpening School by KnifePlanet.net Check out Lesson 3 on KnifePlanet: http://www.knifeplanet.net/lesson-3-k... "Thinning a knife involves reducing the width of the blade behind the Primary Edge from a cross sectional geometry perspective. Thinning a knife is not sharpening, although the same principles are used. We are not working at the primary edge, even though, as Jon explains in the video, one can thin a knife until the primary edge is reached and the result is a zero grind." (from Lesson #3) Thinning a knife is an essential skill any knife sharpener should master.
