I just bought a 7in global oriental chef's knife. The packaging says
that you shouldn't use a steel honing rod and instead should use a $100
global ceramic sharpening rod. I know a lot of other companies make
ceramic sharpening rods, and I wondered whether the "DMT 12-in.
Unbreakable Ceramic Sharpening Rod" or the "Messermeister 12-in.
Ceramic Sharpening Rod" would work. It seems like overkill to buy a
$100 ceramic sharpening rod for a $70 knife (this is my only global
knife).

I also just bought a Wusthof Grand Prix 8in chef's knife and paring
knife and am trying to pick a honing steel for them.
