I love these designer's insight videos, thanks for doing them. I must be one of the few then that only ever use the smaller release cut out on the air. It feels smoother to me as the leverage is so much better. Having said that, when I first got mine my thumb was immediately drawn into that large cut out the first time I went to disengage the lock. I'd certainly miss the little cut out if it wasn't there.
I have one whose scales are dyed red. I think it looks even cooler!
Wow, that looks fantastic. Those scales remind me of my SAK Red Alox Cadet!
