New Work Sharp Ken Onion Mk2 Knife and tool sharpener?

I'm not sure which one I have I will have to double check but after having it I wouldn't go back. I use to use diamond stones and I could sharpen a knife great then I would suck so on and so on now everything is consistent and razor sharp. I use from kitchen k over to my butcher knoves hunting and edc knives.
 
I just bought locally a lightly used KO sharpener and learning to use it. 3d printed a shelf system to get the blades at the right angle, that should help a lot but if anyone has a good video to show their process or steps or that helped them learn to use the thing, post it up..
 
I have a KO with a lot of spare varying grit belts. Mine has 2 different sharpening angle shelf options iirc. It makes quick work when you have a lot of knives to sharpen. You do need to take care not to use too much pressure and trust the speed (which is variable) and grit to do the work. Too much pressure will grind too much area on the blade. Start with less important knives to get used to it. There’s YT vids to watch.
I love the thing.
 
Mine has like 4 different angle settings. There is a roll bar in back to help with the shape of the blade. It's actually pretty easy once you get the feel for it. Just drag backwards at the same speed and stop the blade about halfway in middle of belt.
 
I would get the elite that comes with the blade grinding attachment.

I have the previous gen Ken Onion with blade grinding attachment, and it's an awesome sharpening tool.
