Good stuff. I suppose everybody who processes wood by hand comes to use these techniques. Note that there are no big ugly knots in his wood; that makes things a little more complicated. (At the risk of being picky, he really should be wearing gloves too.)

I was particularly pleased to see he was using a short-handled axe rather than a hatchet. The added reach lets you set up a much safer working situation. The added heft lets you focus on control (i.e., let the axe's weight do the work; your job is to "steer" and determine where the sharp end will come to rest).

Hatchets have their place, but I find it's often necessary to add force during the swing, and that significantly lessens control; combine that with the short swing radius and it's easy to get in trouble. If I have to use a hatchet, I sometimes kneel down to create a safer swing radius.

The sideways splitting technique has limits in terms of the size of wood block it can handle. Also, as he shows, there can't be any length of "overhang" where the wood sits on the block or log that's underneath, because that creates a fulcrum and lever that can flip the other end into your face.
