anybody up for this?  I wonder if the parafilm could stop my bleeding from trying to work that blade.

Parafilm works for me when I try to graft my finger.  

Nice video! I've been doing a lot of grafting onto my mature trees lately.
The only thing I'd recommend in this case is attaching the scion a few inches higher
because if the first graft doesn't take, you'll still have enough rootstock
for another try.
