My Strange Prof. KS Amputator, I now have it renamed and use it all the time in my medic loadout, it felt like an unusual when I found it.
I also found 2 vintages in weapon bot, a strange, also 1 or 2 painted hats in the hat bot.
But then again I'm one of those people that everyone probably hates because I spent all day finding stuff and scrolling through bots.
