>>1461556I guess it can be a tradeoff... If you want to have a nice shape all around, you'd have to change the grind all around--basically because the thickness tapers toward the point. Also, you'll remove less material going with a more obtuse point than the original design. The problem there is the finish just wont be consistent.
So one option is just to grind away along the edge, forgetting about taper. As a result, assuming you keep the same angle, the width of the edge at the point would be wider than the rest of the blade.
