Looks like Blade by Nicholas Lawrence.

Sorry Magic KL, but the fact that the effect is a card splitting in two (Zig-Zag style) does not make it look the same.

With all respect to Nicholas but...
First, the card in Social Distancing is folded (and can be signed) while in Blade it is not.
Second, Blade uses two extra cards to mask the card being split and covers a lot of the card while Social Distancing uses no extra cards and only covers the card with one finger.
And last, while not having anything to do with the visual, the Social Distancing gimmick can be made on the spot in less than ten second and supplies to make more, are basically unlimited. With Blade, you have to purchase the gimmick although as I have not purchased it, cannot claim on its credibility and ease of use.

As mentioned in the previous posts, SD was inspired by DISTANCING by Ade Rahmat and if you take a look at both routines, you could make your initial claim, as the effects actually look identical. However, the reason for publishing SD is the mechanics of the gimmick and the ease of making them.

Kind regards
