Kris blades are wavy, my concern is that the acute angle for the bevel changes with a fixed angle sharpening system. While I can set the angle to sharpen the “ridge”, that same angle would change when the stone reaches the “valley” on the blade because the width of the blade changes. I suppose I could use the rounded stones and change the angle, but my concern is to get an even polished bevel and edge on both sides of the blade. The old timers used to use round whetstones to sharpen the blades, but the edge and bevel were inconsistent because it was done freehand.
