Thanks Alan for the link. Overall, I think the Dave C. video was quite reasonable. (And the first think I noticed during the introduction was the v-breaker tree behind him.)

He's right that light, shallow baton cuts toward the tip of the blade put much less stress on the blade and handle.

The one thing he doesn't specifically point out is to never twist or pry while the blade is embedded in the wood. That is a classic point of failure for a blade. You can see how he see-saws the knife back out on the same plane as the cut, no side-to-side twisting. That's the only safe way.
