I do a lot of slow bike camping in Japan where the campsite will often provide firewood, but it's too large for the small solo stove I have. I've tried a saw, but what I really want is thinner wood split from the larger pieces, not lateral cuts. The axes being talked about are only about 470g, which doesn't bother me too much shoved in a pannier.
