I've never seen a Chopper 1 axe before. It seems to perform well in the video. My concern would be the moving parts. It seems like they would be a weak point in the design that would break before the axe blade does. Knowing axes like I do, the design hasn't changed much form stone axes to flint axes honed to a fine edge to metal axes. It's one of those designs that really doesn't improve IMHO. My take on tools like a knife or axe is that the simpler design the better. If I were to enter a survival situation, I'd want a fixed blade knife and a mid-range axe. No folding knives or weird designed axes that are heavy to swing & carry. If I had a choice, it'd be my trusty tomahawk, my newly hung trail axe, and a fixed blade bowie knife.
