This is very cool. I started trying to use lighter (non-locking) blades for batoning wood a few years back. Pressing the tip into another piece of wood as a 'handle' is a pretty great idea, assuming the piece of wood you're splitting is small enough to allow it.
I posted this elsewhere, but the guy who won season 3 of 'Alone' modified his Swiss-tool Spirit, turning the can opener into a spoon gouge, and i can't help but think that there are probably a LOT of people who would much rather have a spoon gouge than a can opener on their tool. Here's a link to the place in the video where he discusses doing the mod.
While the method shown earlier would be great for improvising a spoon, having a spoon gouge would allow you to pretty easily carve one without having a split down the middle of the bowl.
I'm pretty sure I've seen videos by the guy in the original post. His voice sounds really familiar.
