Compact and easy to use. - Spyderco Tri-Angle Sharpmaker Kit Knife Sharpening System

Great piece of kit. There was a learning curve to using it, so maybe use a knife you don't care too much about first (like a kitchen knife). Good, clear instructions. Beats having to drop a knife off to have it sharpened. I was able to get my spyderco knife ridiculously sharp using this sharpener. Stones are washable, so that's great too. Rating 4 instead of 5 stars only because it'd be nice if it came with ultra fine stones in the package (it comes with a set of medium and set of fine ones). Ultra fine can be picked up separately and they're just a "nice have" and not a necessity. I'd buy again.
