I saw the third YouTube review. This time the lock survived, but the blade broke under fairly harsh use/abuse. He didn't set out to deliberately break it, just push it to its real limits. But I can't guarantee that my fixed-blade Moras and Bucks would necessarily survive that amount of sideways torquing. Still, a useful test to see. I think his main grouch was about the marketing hype.
I'm still ambivalent about this blade. Steel that's perhaps not ideal for hardcore abuse? A handle that more-or-less requires hand protection (gloves)? And why would I choose this over a Fiskars 18" hatchet? Dunno. I'd love to play with one though.
