I'm making a gyuto wide bevel, 210mm in length and a santoku wide bevel 150mm from .09375" stock. I'm going to to a straight distal taper from neck to tip before grinding , leaving the full .09375 at the thickest point. I'm putting in the distal taper before grinding the bevels. What should the thickness be at the tip for both knives before the bevels are put it?
