I ended up going with the Xarilk GEN2. As I liked the clamp better. I got it today and a couple of things were messed up that some folks would be put off by. I was initially. The clamp for the jaw could not be operated because the threads were in the jaw for the tightening screw were full of powder coat. I was able to run the bolt from both sides and clean up the threads. The other issue was, angle adjustment would not work at all, as one of the arms was not connected at the bottom and it jammed the unit. I was able to take that arm off and put it back the way it should have been. But Heck I only paid 80 bucks for it.
So how does it work? Very well for the most part especially on my medium to large folders. When sharpening a smaller japanese paring knife that had a less than 15DPS edge I could not get the arm level as the post was as low as it could go. After some messing around I got it as close as I could and it came out fine. About the change in angle when changing sides, I did notice that and just compensated by releveling, not really a big deal. Also it was more pronounced on thicker blades. The effect was barely noticeable on a thin chefs knife and more pronounced on the Gerber Parabellum which has a thick blade. Not sure why that would be. The diamond stones that were supplied seem to cut well, although the provided 2000 seems coarser than an aftermarket 1500 that I bought, by quite a bit.
Overall:
QC needs help, but it was the last one in stock at $80.00 and deeply discounted.
Works well enough for me. Small knives are probably an issue, however I have not tried yet. On a 10" Chefs knife it is hard to keep a consistent angle from tip to ricasso, due to blade flex at the tip, I think. On the other knives not quite as long it definitely produces a keen edge, as it did on the chefs knife after supporting the tip with my fingers. Both me and the Wife are wearing band aids.
The unit was much smoother to operate once I cleaned the shaft and applied wax to it.
Price is good for what you get, but if you are not mechanically inclined the QC issues would be quite frustrating, I almost returned it until I took a breath and re-evaluated the situation.
6X1" stones are plentiful.
