I seem to have a great deal of difficulty sharpening my Covert on my sharpmaker 204. It seems that the blade is so wide and slopes down so steeply to the edge that I can't get the edge to contact the ceramic rod properly.As a result I get uneven contact and lousy results. Anyone else find this to be so? Any ideas on a different method of sharpening this knife? I should admit up front that I am pretty inept with bench stones. Thanx.
