If I could give this zero stars I would. The channel portion does not work at all. I saw a beautiful carved orange on YouTube. This knife would not break the skin of my orange. I used a paring knife to make a slit, but it still wouldn't cut at all. Then I tried a cucumber since it has a thinner skin. It wouldn't cut that either! I suppose I might have gotten a faulty one with a dull blade. I will definitely be returning this. So much for a nice stocking stuffer for my son who loves to cook.
