He gained 25 keys, but also seemed to have sold this for 10 keys: http://www.tf2outpost.com/trade/13603035

This all means he got 15 keys (I think)

http://www.tf2outpost.com/trade/13324806 - SF Knife, other guy added Black Veil + Black Tooth Kicker + Archimedes = 16-ish keys

Side note: Took mid-price of Knife since it was offered on
