When it comes to this kind of split in half, it's as rare as it's odd.
And I mean not only odd to look at (compared to basic modularity such as headless or waist split in half), but most of all odd to experience. More surreal and diziness-inducing, I find it intriguing and fascinating.
While S&S duo did Vertical Sawing few times in their showgirls career, none of them liked this feeling. Whenever they did it at home, it was either as rehearsal or out of curiosity. Usually naked to easily avoid ruining good outfits.
To be honest, this effect looks the best from an angle where nose is easier to draw and stump is visible (unless it's obscured by the blade). And while there's no time in my schedule to make singular Vertical Sawing trick animated this way, it was very tempting to capture Vertical Swap, and even more tempting to add some paragraph to it.
