I did a couple of these video a while back with the exception of one. Using the diamond sharpeners is the newest video in my knife sharpening how to videos. It was done mostly as a review for Smiths. When I do a review video I try to do the best I can with the explanation of the product then move on to an actual demonstration of how the item works. In this case I used all six sharpeners to put an edge on my blades.
This is one subject that gets a lot of scrutiny because there are so many different ways to do the same thing. I did this with hair popping results, you cant argue with that kind of outcome. If it works it works. Watch the videos, I hope learn something from them and above all please enjoy them! Thank you!
