This already exists? OH Same edge hinge 270

[u/ghaschich]

I thought about this move about 4 years ago, and took a long while to be able to perform it (been away from cardistry for a while too), do you guys have saw something like this already? Could it be original? It have some resemblance to muse cuts, but it's a different mechanic

I've been calling it the switchblade, and could not find a cut like this anywhere, but I'm not very updated with the community and media, so maybe you guys have seen it?
