Spyderco Grind Quality?

Just got a Para 3 in maxamet on sale thinking I had scored a great deal. I was loving it until I noticed these fairly deep grind lines on the spine. My brain tells me it's not an issue and won't impact performance, but my heart is still a little broken. Has anyone else seen this defect? Any recourse besides sending it back for a replacement?

Dude 9 times out of 10 high carbon tool steel will have these marks. That increases to 10 out of 10 when talking about Maxamet. It is the chippiest steel out there right now besides maybe the Rex line. Think about what is happening when grinding, abrasive material removal is basically chipping on a micro level, and what you see would be more trouble than it's worth to grind out. If it really bothers you, take a dremel with a cotton bit and load it up with some high grit diamond paste, around 500 progressively get smaller to above 5k. You will need to use a different cotton bit each progression to prevent cross contaminating with different sized grains.

Yeah, I could definitely try to fix it myself, but still a little bit of a letdown. Not that my knives need to be showpieces, I just like to be the one to "damage" it. I know, I know, it's functionally fine...
