Can someone please ID this trap?

I saw this on YouTube a while back and can't remember the name of it. Does someone know what this is called? I'd like to look it up and see if I can do it better. I made this one from memory and put it up in the garden. Not sure it's 100%, but works okay. I want to read up a bit more on it... but need a name.

Looks to me like a variation of "figure 4"

This must be it or a variation of it. Interesting I remembered the trigger stick notch being wider than the Google images of a Siberian deadfall show. Will try it both ways and see.

Thank you
