Can't align Kershaw Cryo with Lansky System

[Azaex]

I'm learning how to EDC and maintain a few cheaper knives before I get to something nicer; I just got my hands on a Lansky system, which is hilariously enough more expensive than the Kershaw, but I figure it'll be a good skill to build up on something cheaper.

I can't seem to align the Lansky to my Cryo's hollow grind though. If I hold the blade up to a light surface with a hone touching the edge, I can very clearly see that on one side, the hone touches the edge, and on the other, the hone impacts the unsharpened part of the blade without actually touching the edge. Flipping the blade over in the clamp does not solve the problem; the problem follows the edge of the blade. Moving the blade in and out of the clamp does not solve any issues either, and the putting the guide rod even at the 30 degree hole on the problem side doesn't solve the issue. Am I doing something weird?

I've aligned my guide rod, quadrouple checked the clamp, and I'm still left here scratching my head.

It could be several things. The cryo may not be ground symmetrically (even though it looks fine to the eye), which is actually pretty common for knives, regardless of price. I would say to check the clamp on the lansky for clamp tilt (the imperfect nature of clamping systems sometimes tilts the knife in the clamp, or mis-aligns the whole device), but if I'm understanding you correctly, the stone touches on the same side of the knife no matter which direction it's clamped? Since you're new to this stuff, I'm assuming you don't have access to an angle cube to check your angles. You may be able to eyeball the angle with a protractor, or rig something up with a protractor to double check the lansky angles. Is something perhaps bent out of spec on the lansky? This is where an angle cube would help to verify things. Lastly you are clamping the cryo evenly in the clamp, on preferably a flat area of the blade so it doesn't try to lean to one side? In situations like this, I use an angle cube to check things. If that all turns out fine, I assume the knife is ground asymmetrically from the factory, and, either return the knife, or start at a high angle, 25 deg or so, check my work, and work down from there. Another thing, those angle markings on the clamp systems are just guideposts, they are sometimes pretty far off from the actual angle. Just some ideas.

the Kershaw cryo spine is not square with the edge, a lot of kershaws aren't they have false edge spines meaning they are ground to look like they have an edge there. I do mine freehand and the best advice I can offer is to find a way to shim it or go to the flats on the blade to use the device.
