Well, that happens. I would bet that Busse would fix it for you. On the other hand... I tend to see stuff like this in some form or another in almost every single knife I've ever seen, barring some lucky shots and some very expensive customs. Look closely at your knives, and you'll start noticing slightly or less slightly asymmetric handle scales (one of the scales is slightly longer, thicker or just the ends are rounded differently than the other), blades off the center (yes, this happens a lot in fixed blades, too) of the handle, uneven grinds, and what have you. Fällkniven, Busse, handmade puukkos, Bark River, Spyderco, whatever, they all have a LOT of it. Some are relatively hard to notice. Some are easy to notice, like, I assume, your case. As long as it doesn't affect performance, I don't care that much. Seriously, it might be enlightening to carefully go through some of your knives looking for stuff like this. You'll need a good light in the room, and a sharp eye, but this stuff is there in a LOT of knives. Not in all, but I'd wager that in most.
