Just in case you don't have time to watch the video, here's the punch-line: I would recommend the single hole long point if you are looking for something that produces a pointier point than a standard sharpener but is still very easy to use on the go and is cheap. If you are more into the sharpener experience, then I would say go with the Masterpiece and use it while relaxing at your desk.
