Hmmm - 'teach a brand new method?'
It would be a challenge to develop anything brand new when it comes to 'stealing' a buckle/banded watch.
So, brand new - nah!
Now, does he add his own 'touches' that may add a variation to the regular technique depending on what you already know above the 'basic method?
I think so!
Remember, it's not about knowing methods. It's all about being able to 'do the trick'.
The great performance - that's the challenge.
