This unobtanium tool set is Phil Wood's first tool ever, designed to work with his first version hubs. This is the tool mentioned on Phil Wood's tools category as their first tool. This set was owned by a lifelong bike shop owner. I was told it removes hub axles, pulls bearings, and can even be used to press them back in. I've never seen another one. Here it is on Ebay, I suspect the bidding will be fierce!
