I went on a long hike with some friends recently and found this trick as I was walking around. I was carrying something in my left hand, so I kept trying to find one-handed yo-yo tricks I could do with my right hand. I ended up finding a nice back-of-the-hand stall that also worked well with a responsive/counterweight set up.
These types of back of the hand stalls aren’t knew, I just like the aerial toss into a stall. You can see another version a counterweight back of the hand stall in this old video of mine too (around three minutes in).
