Sounds a bit like fishing, right? Definitely not knitting. While splitting firewood, my wedges got stuck in a knotty piece. Only one would be hammered out. Brilliant idea: use the chain saw. Look what happened:
Wedge and chain saw stuck! Brilliant idea #2: use the pruning saw to cut out a chunk.
It gets trapped, too, but I keep sawing. Success!
After a bit more judicious use of the chain saw, its three pieces will fit in my small wood stove. My rolling "wood box" resides in the attached garage between splitting and sawing sessions, saving trips into the rain for wood.
