The main criticism I have of my own (cheap?) flarenut wrenches is
that the hex (flats) is significantly recessed (i.e., countersunk)
with respect to the sides of the wrench. Since a flare nut itself can
be somewhat thin (and only accessible from one side), these wrenches
tend to contact only a fraction of the already meager nut thickness.
I think this can contribute to rounding off the nut.  I wonder if the
"good" flarenut wrenches eliminate that recessing?
