In my previous kendama videos, I've certainly tried to incorporate things that I've not seen done elsewhere. Alternatively, failing that, I've tried to present more commonly known techniques in a way that might not be expected. If you think about things in the right way, it's quite easy to do that, even if you don't have extreme levels of skill. Just mix up ideas from lots of different sources and see what happens. Yet, ultimately, it's hard to know whether anything is really new.
Actually, I'm not sure it really matters that much. Over the years, in the context of using others props, I've seen loads of "new tricks" that most certainly were genuinely new, but were not necessarily any more interesting than stuff that was already out there. Instead, I think that it's better to be thinking 'how can I make this more watchable?', rather than worry too much about whether any particular core technique has been done previously.
