Keyring rename tool
Keyring/bag rename tool

Sir, you have piqued my interest. I can script this easily and have vendor stones that will sell you renamed bags or keyrings. My only worry about this is that it can be 'exploited' to troll people with the vendor search.

The first thing I'd do is buy a keyring and name it 'a castle deed' and put it for sale on my vendor for 100g to trololololol. Maybe have some selectable names. I can get around this by appending the name to the end of the keyring, maybe.
