I appreciate the suggestion, but as mentioned, I am not bothered by this. The screws do their job just fine, and I am not OCD enough to care about the appearance, which is basically something you gotta look for to notice. The purpose of this thread is just my curiosity as to whether this was a purposeful design or just sloppy manufacturing as it seems to affect the balance of my 21s. It seems that the concesus is that it's the latter.
In my fan-boy mind I will continue to pretend this is some unpublished, and fantastic feature to make the knife that much better!
