I have posted before that we didn't have any luck with the supersharp blades when we tried that. Might just be us. But never doubt the quality and endurance of their sharpener. You can change hook angles, change pitch and depth of grind (through different cams), different widths. Its easy to use. Woodmizer may have a more "pure" grinder with their new one. And for some people that will be the cat's meow. But with the Cook's, when you have to change hook angle due to going to frozen logs, its a snap. You can try different blades with different teeth spacing, simply by changing the cam. Try different gullet configurations. The price can't be beat. Not sure what year we bought ours but its got to be at least 13 or 14 years old. If you want a versatile grinder that gets the job done, it will.
