As for 9/16" wrenches you certainly need at least two if only so that
you have one to work with after you have dropped one down in the bilge
and can't fish it out :-)

Make that three, because you sometimes need one to hold the head
of the bolt while a second one is turning the nut (assuming not enough
clearance to get a ratchet on either). And count the one which went in
the bilge

But more realistically, there are a host of jobs that you simply
cannot accomplish if you don't have the correct puller, spanner,
whatever.

Agreed. Or unless you modify spare tools to make the special
tool which you need. :-)

Enjoy,
