I received the MK.2 about a couple weeks ago. I have since been able to sharpen all my hunting knives, some pocket knives, and all my wife's kitchen knives. There is a QR code on the front of the box with launches a demo video to show you how to sharpen all the different knives. After watching that I was good to go. Being a guide, I've been used to sharpening everything with a wet stone, which is great but takes a lot more time. I found I was able to shave with each knife after not much time. I loved the time savings! I will still bring a small sharpener to the field with me when I'm away from electricity but this is a good one to have in the shop at home.
I don't really have any complaints. I was able to sharpen 10 knives in about 15 minutes. I am missing a patch of arm hair where I was testing the sharpness! The only difficult thing was keeping the blade on the guide, not at the correct angle but the blade edge itself on the little shelf, especially on curved blades. I don't think this is a huge deal, I was still able to get the results I wanted quickly by controlling it in my hand.
If you're looking for an electric knife sharpener this is a good one to go with! You won't be disappointed
