Jeff,
Sorry for the delay. I understand the new grizzlies have a much better factory grind. Are these the ones you have? Or are they the older ones? (you can tell by looking at them)... the new ones are laminated all the way to the back, and the older ones are only laminated about 2/3 of the length of the blade.
Either way, I'd file them first before using the sharpener and you'll need to do it free hand. I can't find a good file to work with the knife sharpener. Since time is short, give me a call tonight between 6-8 eastern if you can. or send me a PM with your phone # and a good time to call. Thanks,
Ron
