I got this Tom Kuhn Heirloom Box off eBay a while ago before I really appreciated what it was… and how it is a short trip through yo-yo history. ![image](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/a/c/4/ac471888ce2e4828de4bedf8c69b009c91ac857e.jpeg) - Two 3-in-1s, Smo-Bro / butterfly and Diamond / imperial (1978) - SB-1 wood sleeve but metal body (1984) - SB-2 ball bearing, metal body, friction stickers (1990) - Two ball bearing woodens, Sleep Machine / butterfly and Roller Woody / imperial (1992) Kinda crazy that the two wooden bearing models came _after_ the SB-2! I am not a huge fan of the way you have to manually dial in the gap on those two, it reminds me of the eH, and I feel like the attraction of yo-yos of this era should be simplicity… and that ain’t simple! Still, it is really cool to have wooden metal bearing yo-yos and I need to spend some more time with them. ---

I figure after 1992, things were kinda static until the 1999 boom?

I think! A handful of the more limited No-Jives were in the butterfly configuration, though I have no idea how many or what models specifically. Maybe @edhaponik can weigh in? ---

If it has a wood axle then it definately comes apart…BUT the pog/lens has to be popped out. If you excert too much force that wood axle will snap. Those were the best performing wood axle yoyos ever…for about 5 minutes. There is a knurled brass nut under the pog that holds the whole thing together. Don’t attempt to unscrew it like a modern yoyo. ---

Well well look who showed up… ![IMG_7328](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/6/2/7/6273371c334c36a111a54a3313082dd29aba51b0.jpeg) It is still hard to tell what’s going on with the axle of this Pro-Yo 1. Ah wait. I took the string off and it is **definitely a full metal axle** , not a wood transaxle. ![image](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/6/1/f/61f51ac680009bae5235acd53d8abdccec6453d0.jpeg) So the Pro-Yo 2 - screws apart in a rational way - uses a wood transaxle, not a metal axle - has _large_ wooden sides on that transaxle for a “wooden response area” In addition to verifying the metal axle, I see zero provision for any kind of response inside the pro-yo 1, no starburst or anything, just the (one piece?) metal nut that makes up the metal axle. ---

@codinghorror 1. the proyo2 is not a wooden transaxle. Think of it more like a tiny one-piece Flores yoyo hugged in perfectly formed plastic bodies to make it feel modern. Those high wooden walls kept the halves parallel and helped with response. The curved axle area helped solve the fragility of the proyo1 wooden axle but hugged the string too much and caused more friction and less spin than the proyo1. 1. the proyo “1” has a brass “hex axle” to solve the problem of rotating halves (the endless pursuit of early 20th century yoyo engineers, actually the subject of the very first U.S. yoyo patent). Your proyo “1” is riveted or does it have the knurl fastener? ---

@codinghorror btw we never played proyo1 with the pogs in place. We played pogs off to have access to the knurled fastener. ---

@codinghorror the brass hex axle worked, just had a narrow range of operation vs string tension. The wood axle gave a much wider range of operation for string tension. The knurl nut looks like a brass disc with ridges around the perimeter. If your yoyo had it you would know it. ---

I popped a thin poly string on the Pro-Yo 1 and took it for a spin … wow, yeah, **the Pro-Yo 2 is _dramatically_ better**. You weren’t kidding @YOHANS! Big big difference in play with the wood transaxle and wooden response areas versus the plain plastic and metal axle. > [@YOHANS](#): > > Those were the best performing wood axle yoyos ever…for about 5 minutes (I think I might have messed up my Pro-Yo 1 a bit by trying to _relatively_ gently unscrew it… the plastic halves shift a tiny bit at the apex of every throw, not sure if that’s making it perform unusually badly.) Honestly the Pro-Yo 2 is still a good enough player that selling it for $4.50 new, as YYE does now, makes total sense. I’d argue it is clearly better than a Duncan Butterfly XT. And you can unscrew and potentially repair it, too! ---
