I'm sure that what it is. My grandpa took care of a park many years ago and I'd go along with him as he speared scraps of paper with a stick and that point on the end of it. Heck I wanted a job doing that when I grew up as it seemed like good honest work. You don't see people doing that anymore in a park.The tip off a litter-picker pole.
Alternate guess - the tip off an ice fishing pole.
