"Oh yes, try this on a piece of old growth hemlock fir, the kind with a 1:20" grain twist and three knots per square foot circumferentially. That was the kind of stuff dad would bring home for us from the Weyerhauser reject pile to cut up into firewood, the kind that took 3 wedges and an 8 lb maul to get through."

Or chewy red fir. I remember 3 wedges from both sides of the round and a maul. Almost lost the wedges.

A rented log splitter works everytime.
