http://www.tf2outpost.com/search/129673712 5 trades on OP.

2 of them are sellers of sets and the other is a buyer with no info on the Handle.

http://www.tf2outpost.com/trade/12365911 Selling for 3 ref, no takers. I wonder why? Doesn't prove anything, other than that this isn't a valuable UC like the Hot Dogger.

http://www.tf2outpost.com/trade/12415253 Offer of 2 ref on a green painted one, paint can't prove much, and it was turned down. No other offers, this one proves nothing.

Now you may be asking "B-but Soma, why would you try to change the price if none of the trades show anything?"

Well, there's this trade.

Sold for 1 ref.

For an item with little to no sales, I hope this is sufficient.
