I've been using cheap stones to sharpen my pocket knives and my wifes nice kitchen knives. I'm looking at the spyderco triangle sharpmaker and the wicked edge setup. Is the wicked edge that much better? All the reviews are very positive and it looks easy to use. Will the spyderco be just as easy to use or will it leave me frustrated? I've seen mixed reviews with the sypderco, too. Thanks for the help/suggestions.
