LATEST (UNEVENTFUL) UPDATE - 12/28/2014:
After several more attempts at getting a response, he STILL has not given me a response after he requested photos of the knives from me. Again, the pictures that I sent him proves that there's no way I could have even attempted a "switcheroo" since my other Avo has a later lockup, and does not have the distinct scratch on the same location on the blade, while the scratch on the knife he sold me occurs in the same location on both his and my photos. Maybe he realizes this and has just decided to take my money and run.
I have informed him of this thread weeks ago, and he chose not to come to defend himself. All he has done so far was ask for advice on his Instagram page, where he was suggesting that I either have buyer's remorse, or am trying to scam him.
If anyone deals with him, my advice is to get high resolution pictures of every angle AND in different lighting conditions, rather than trust his word on an item's condition. Or better yet, just avoid dealing with him entirely. I'm not sure if paying with Paypal goods would have made a difference since the blemish/scratch may very well have been part of the manufacturing process, and the knife may be in fact, "new," though not accurately and honestly described. Either way, dealing with this guy has been nothing but a waste of time, and it just pisses me off every time I see that mark on the blade of the knife.
Looks like SW process marks. I have had that in a couple of my midtechs even some Hinderers. The lint under the clip does not show usage. If it had lint inside the scales then yes I would agree with you it is used or very poorly stored.
BTW if you ever want to sell that TAD snafu let me know

good luck resolving this!
It could very well be stonewash processing marks, but it looks enough like a scratch since it's a line that is almost half the width of the blade in length - right smack in the middle of the blade. I think something like this should be noted from the ad from the beginning so buyers know what they're getting into.
Oh, and that TAD Rassenti is a Dauntless... Not a SNAFU. Similar, but different.
