Razor blade

Yesterday, Caveboy and I (and Caveboy, Jr.) walked around the lower East Side liberating stickers in 90-degree weather.  At one point, near Rutherford Park, as “we” were climbing a walk sign, two guys in a furniture truck called out and threw a razor blade in our direction.  It was slightly unnerving, until another guy nearby picked it up and said we should use it to cut the stickers off the pole.
