What is the author's rebuttal to the argument that there is no point in analyzing a tool once it has lost its sharp point?

The author's rebuttal is that most tools start off with a rounded edge due to an edge hone, and the shape of the hone matters. The ideal geometry can vary based on the material and cutting conditions, and a model could be developed to determine which edge shape goes with which product and what the tolerances must be.

What is the significance of the paper by Astakhov, mentioned in the text?

The paper by Astakhov points out many flaws with the 'single shear plane model' referenced in the original post and introduces the 'slip line model', which is further elaborated in the paper by Ozturk and Altan.
