Even beyond the obvious history of certain rare and discontinued weapons, there's personal history for Dahn in there too. Some of his spoils were particularly hard-won—for instance, one item, a rare AWP rifle, caused him so much trouble that he had to get the police involved. Also, er, a scammer's mom.
"You may notice a couple items in my Item Showcase: AWP | Dragon Lore (Factory New) and Bayonet | Fade (Factory New)," Dahn wrote of an incident where he csgo skins cheap nearly got scammed out of hundreds of dollars. "These items have the name tags of 'Kainoa's Gambit' and 'Kainoa's Regret' respectively. On September 5, 2014, I attempted to trade with a user from CS:GO Lounge for an AWP | Dragon Lore (Factory New). This user, whose username will go unmentioned, has a first name of Kainoa. After I sent the Paypal payment, the user ceased communication, and even attempted to fight the Paypal dispute that followed."
"After I spoke with the police from his city and called his mother at work, he re-initiated contact with me. We made an arrangement for the AWP and the knife (as a bonus for the hassle) to be transferred to my account, and I cancelled the dispute and stop-payment on the transaction. These items will forever bear the monikers of 'Kainoa's Gambit' and 'Kainoa's Regret' to symbolize a lesson learned."
