Thanks Larry. I use a professional butchers' filet knife (the same as our butcher uses, bought at a butchers' supply warehouse) and a professional 3-stage electric knife sharpener, and have no trouble fileting rockfish and other species. Maybe my problem with fileting redear is that they (at least the ones I have caught recently) are the smallest fish I have ever tried to filet and I am trying to get more meat into the filet than I should reasonably expect to get. Thanks again, Larry, and you are so right about redear tacos.
