Poles and chainsaws?

At the O’hare International terminal, I was killing some time before a flight and noticed that at the check-in counter of LOT, the Polish airline, there were “No Chainsaw” signs posted all over the place (you know, picture of a chainsaw, big red slash). I think I counted 6 signs scattered around. None of the other counters had these. Is this a hot item to bring back to Poland? Is this a coup d’etat in the making? What gives?
