You have a "hunch" because it's listed under ffxi.cannotlinkto at http://ffxi.cannotlinkto/itemdb/display-item.php?item=5253 as well as mysterytour at http://mysterytour.web.infoseek.co.jp/ffxi/us/guild/009Woodworking.htm near the bottom.
Your hunch seems to be reading other sites and posting on here.
