I know purchasing clones is frowned upon for many reasons but my buddy bought a Spyderco para 2 off eBay (thinking it was legit, just under priced for the explained wear on the entire piece). Obviously he gets the blade and its not authentic, but we noticed that the grind has a white line above the edge. Not really distinct white but like an area where there is a foggy patch between the edge and the flat grind before the edge (I can get pictures to better describe this) but i was wondering a couple things because i cannot find ANYTHING on this. 1.) What causes this? 2.) Can it be fixed, and how if so?

Thanks for your time,

Dustin

I'm not with him at the moment, but this picture is a pretty good reference. If anyone could explain what makes a good grind too that would help. It seems like something went wrong in the process, i don't know though and i don't even know if it can be fixed or what it is! Its bugging me though.
 
Chances are it has been taken to a buffer to sharpen the edge and it hit that area
 
Yeah it seriously had me questioning if the blade is hardened, is there any way to test that? How would I fix it if it was a buffing wheel that caused it?
 
"Brass Rod" test the edge to see if the edge bends and returns to straight. Do this by laying the flat edge against the rod press enough to see edge deflect have a light shining at the edge otherwise its not easy to see. If it bends and stays too soft no heat treat?

Scotch Bright pad might fix the scratch pattern if it was buffed.

Hmmm, great feedback. Kind of confusing (just because my lack of knowledge). I'll research and and test and come back with results :) Thank you SO much, i'lol let you know what happens and if anyone else has input let me know.

This picture of a different blade shows it even better, let me know what you think it is!
 
I'm with AVigil. After sharpening the knife, they knocked the wire edge off/gave a final polish on a buffing wheel or similar.
 
that would make a TON of sense. I'm assuming it saves time or labor, but is it fixable? Just scotch pad is the best answer?

You could try to blend it back in with some scotchbrite material, or a fine grit abrasive paper. Might have to finish the whole blade though before it's all said and done, just to make everything look even. Alternatively, you could just buff the whole blade and even it out that way.
