I have a Kropp that near the round point there is some cracks and black spots. The rest of the blade is in superb condition. I still shave with (honed it this morning) and looks great. To cut of the round point to make it a square would a dremel and a cutting disk suffice? Would this cause damage to the rest of the blade or warp it due to the heat? If i can use this, what steps afterwards would I take to make it look nice?
