Honestly the Park tool shown (and clone, 100% as effective) is worth owning. Sometimes those things can be stuck worse than a curse and as long as you can lock it in place with a bolt and washers it allows you to safely apply the most force in the most controlled fashion. I do have a large wrench that would work, the dedicated tool and the way it grabs all around wins.

There are some tools where it pays to get a Park tool branded one, this isn't one of them.
