It's probably a pike pole head. You don't roll logs with pike pole, you stick them and pull, or push, the hook is also used to pull. If the logs are being water scaled, then the scaler rolls the log using his caulk (cork) boots, other wise there is no reason to roll a log. Pike poles are used in log ponds, and used to be used when rafting logs in rivers.

This is a pike pole with a 10 foot wooden pole, they make them with hollow aluminum poles now days that are a lot longer than 10 foot. The last picture is a modern replacement head for an aluminum pole.
