Whoops! Thanks for catching my imprecise description.  As you describe,
three separate bits: Chain Whip, Lockring Tool, Wrench.

Oh, and torque.  Gotta have torque...

As far as preferring a freehub to freewheel for removal...For some reason,
grease and such appropriately applied, I've yet to have a freewheel which
didn't have to be taken off via the "clamp the tool in the bench vise
(secured by the slightly loose QR) and turn the wheel method."

Of course, most of those were mtb freewheels, and low-geared climbing will
get those things on, but good.
