In my opinion you shouldn’t buy this coarse of a stone for 99% of any knife sharpening sessions. The exception being if you buy unfinished blank high HRC blades and are doing initial bevel creation (I am doing this). The real value of this stone is in blade thinning. You can do minor blade thinning on fixed blade systems by lowering your angle 5-10 degrees lower than your sharpening angle and removing steel until your scratches are just at the top of the secondary bevel. You then raise the angle back to your desired sharpening angle and proceed. Depending on knife geometry you can thin 5-10 mm above your secondary bevel. These CBN stones excel at rapid steel removal and their thermal properties help keep temperatures lower thus preventing the degrading of steel hardness that comes from rapidly removing steel during sharpening or thinning.
