Maybe it is a Zhor, but it almost reminded me of one of the customized wedgies I played later on the same day, or maybe a spyder. It had a crazy coating that almost felt like the outer soft plastic/rubber like coating of a cell phone, but obviously much more grindable that a cell phone coating. I know that this was the duncan prototype, as it was someone’s who is most definitely in the loop. It was all black, kinda undersized but not really, and I dont think it had much, if any, markings on it. I dont remember spikes, but I didnt play with it for very long, so… I was really, really taken with it though, its a fun yoyo. If any of yalls have more info, please let me know.
