Riffing off the ring:

The Hand of Holding. When held, it can hold items for you and allow to use them with whatever ability you would normally have. Technically helpful in slightly extending your reach, and depending on the niceness of the GM may also mitigate curses or other effects that are triggered by holding the item, since you technically aren't. You are still essentially wielding, using, and various other verbs-ing the item, so those still hamper you.
