Video Games Traded #Profit

I traded my
M9 Bayonet | Case Hardened (WW) : 110-130$
AK-47 | Case Hardened (FT) : 19-23$
AWP | Man-O'-War (MW) : 18-20$
For a Karambit | Stained (FT) :190 - 210$
By the way the case hardened hardly had any blue for the knife so it was still market price, the AK-47 probably had only 30% blue PS so I didn't lose any profit from that. Plus I was trading from school on my iPad xD I couldn't wait to get home.

I'm not so sure if there are patterns for stained skins.
