I'm thinking either One Drop, Caribou Lodge or String Theory.
Boyd Seth used to compete in tops sponsored by Caribou Lodge and at one time told me they were planning a signature top for him. But no, none of them made these tops.
Another possible company would have been Ethernal Throw. At nats last year Free said he would like to come out with a top after his yo-yos got some traction.
How about Richy and the Chico guys?
We have a winner!
Chico Yo-Yo Company (CYYC) is behind these tops. The top was designed by Thad Winzenz and Richy.
I have never seen Thad throw a top but it seems he is a decent player.
I bet one of those aluminum body tops will end up in the National Yo-Yo Museum
How about a name for this top.
I like Milk & Cookies ?
