Looks like they missed on a couple pin rounding attempts. The main blade edge is a bit wonky, but pretty easily fixable, the secondary blade looks like it was sharpened by someone having the shakes

BTW, I have a Case Bose collab knife where the shield is so proud I guess half of it is above the covers, and it snags the thumb while gripping the knife. That is the only flaw, and I believe it to be the reason the original owner sold it on the exchange for such a fair price( though I have no evidence to support this thought)...I plan on using it and dismissing any concerns about it as it's only a knife...
This took me by quite a surprise, and it left a sour taste on a couple levels...however, this knife was purchased for my wife to gift to me at Christmas...so there is that to deal with. Everything else about this one is excellent, but that shield fitment really put me off, put a kink in my jaw. After letting it sit in the closet in its pouch for a couple years I pulled it out and said to myself, well, why not just use the darn thing? It's just a knife after all. And as a "just a Knife", it does what it was built to do...nothing in this world is perfect, some things are good enough, some are better, and some are worse. I don't pass my duds on to others to save my expenditures, if anything, I'll just give them away to someone who may see them in a different light.
P.S. this is the poorest fit I have ever seen on a shield in all my knives, and it is on a Case Bose collab!
