For the forumers interested in the BSI sharpness definition I am attaching the original paper referenced in Larrin’s article. The BSI (Blade Sharpness Index) paper is worth of reading provided you can digest the formulas.
BSI sharpness is calculated from energy (work) necessary to initiate a cut of a test medium. To get this energy we need to integrate (sum up) all elementary products force times displacement along the cut initiation path.
