Without seeing more of the knife I wouldn't have thought it was a very expensive knife. The way the light reflects off the handle doesn't make it look like a very smooth radius or at least not a refined finish. Plus the flaw you point out. I would be curious what the side of the blade looks like. I can't imagine the plunge looks anywhere near the same from one side to the other. But without seeing it, just have to try and imagine what it looks like from the side.
Not sure what the point of keeping the knife a secret is. The price point makes a big difference as to how big of a deal it is. And if a maker lets a knife leave their shop looking like that then people deserve to know about it, especially if it is an expensive custom like some think it is. I'm sure the OP would have been a little more cautious buying the knife had they read this thread a month ago and it showed which knife it is. If the knife is revealed at least other owners can confirm if it is common or not.
