I was impressing various students at my school by showing them various twisty puzzles when one of them recalled a puzzle they owned. I thought I might have seen it somewhere, but I may have been thinking about something else.
He said it had some sort of gear mechanism, and was a two-by-two cube. But one of the key features of this cube was this: you could pull it apart on one of the axes, and turn the parts separately.
I showed him the Skewb shift, the only puzzle I was aware pulled apart, but he said that wasn't it. Exactly one axis pulled apart, and also, it was two by two.
Anyone know what cube this could be?
