ROM hacking tools... key item descriptions

So I've used FF Hackster many a time before. I've done a rather thorough hack of the game for my own amusement, and by thorough I mean I changed all the dialogue, spell and monster names and added a Hastega spell in place of one of the eighth level instant death spells, and... well that's it really.

But there's one thing that's always bugged me. No ROM hacking tool I've found specific to this game seems to have ever had the ability to change the key item descriptions.

Does anybody know of any such utility?

Maybe one day we'll have a spambot who advertises it.
