Query: You could do better.

If you had two rocks and one of them was sorta flat, you could put a piece of fruit on one of the rocks, smash the rocks together, and extract juice. You could also put a bucket on the ground upside down, put the fruit on it and hit it with your forehead. Another way you could get juice out of a grapefruit is to take it the the gym and drop barbells on it while making angry juicing noises.All of these methods would be better than this piece of metallic evil finger slicing death machine.Don't bother. Use a knife and a reamer or your friggin' hands. This thing doesn't work well at all and you can only extract about half the juice out of a piece of citrus you could with any more traditional method.
