I would need to double check w/ A-RT / One Drop but I think it’s actually fewer than I previously thought, which was all but the bi-metal like you said. When @DocPop visited them recently and toured their playable museum, One Drop manufacturing for A-RT came up (timestamp link) and it sounded like they make:
- 420/420 light
- Grail/B7 Grail
- Quail
- Dale
- Garrett
- something called the “cube”(??)
They specifically mentioned that they didn’t make the DK and there was no mention of the Sucction which similarly has caps. I feel had they manufactured the Sucction it would have come up when Shaun was listing they ones they make since it seems like it’d be a memorable yo-yo to machine. There was no mention of the Fe/urn (unless that’s the Cube??), Life (I think these are made by whatever machine shop makes G2 yo-yos), or 69. But it’s also entirely possible it just slipped Shaun’s mind while they were going through the shelves since it was a very impromptu thing.
