I'm a still rather new to honing and have acquired a free blade with a slight smile. I have been trying to hone this thing for a while and can't seem to get it. The back 1/3 of the blade is super sharp, hanging hair test sharp. The middle third barely shaves hair at all, and the end of the blade would only be useful for cutting butter. I use the technique for smiling blades and have even focused only on the tip to just try and get it sharper, but have failed. I do notice that the spline at the dull end of the blade has at least twice the hone wear as the sharp end and it was that way before i started honing. Any thoughts to get this bad boy back in action?
