The micro bevel

Only the shape of the cutting edge in the immediate vicinity is critical for the quality of the cutting edge. Therefore, you can grind a small additional bevel here (on the main bevel), which has a slightly larger angle than the main bevel. This is then the actual cutting angle. Such a small volume is ground off relatively quickly. Therefore see also: Longest possible micro bevel strategy.

Please note: with this design, the cutting edge is on the plane of the back side. So you can chisel out a flat surface well. This is different for the rear micro bevel.

Please note: if you want to use the trick, the main bevel must be a little more acute than the desired cutting edge angle.
