Dave,
Grizzlies must be filed before you can try to sharpen them with the knife sharpener. If you can get them somewhere near sharp with the file, the sharpener will finish them up.
To duplicate any factory bevel with the knife sharpener, color the bevel with a permanent marker, then eye-ball the angle as best you can and take a few swipes with a dry stone. Look to see where the stone is removing the ink. If the ink is gone from the cutting edge but not the shoulder of the bevel... That's telling you you have the angle set a bit too high... If you're taking ink from the shoulder of the bevel but not from the cutting edge, that means you have the angle set too low. Adjust the angle till you're getting all the ink off. It's better to error a little on the too high side than the too low side BTW.
Give me a call if you need some help. Thanks,
Ron
