Pros: Durability, Ease of Use, Effectiveness, Overall Quality
perfect angles for a perfect cutting edge.
Take the time to review the video and read the manual. Go slow at first to get the feeling of the system. You will find that a black marker is very useful considering knives never have the same angles and the same knife might have two different angles. That said this system will get you to your goal. I wish it would of had a clamp to hold the knife. That would eliminate human error all together but it would slow things down. Cutting is an act of "Force" not sharpness. So you have to find a middle. I got it to the 1000 grit and it didn't cut as well as when I get a paper slicing 600 grit edge. So you have to play with it a bit.
