In Koppel v. Hebrew Academy (191 AD2d 415 [2d Dept 1993], lv denied 82 NY2d 652 [1993]), an infant plaintiff who was climbing upon a 10-foot cyclone fence surrounding the defendants' property cut her hands on what plaintiffs alleged to be the very sharp ends of the top of the fence. The Court granted the defendants' summary judgment motion and held that (at 416) "[t]o hold that a landowner must maintain a fence so as to make it safe to climb over would encourage people to do so, and would defeat the very purpose of the fence."
