That was a great video, that really shows what a traditional can so.
But.......... I don't know if everybody here knows much about willow trees, but they're incredibly easy to cut. If you happen to be in a place where there are no willows, you might not have that same level of success. Where I spend my time outdoors, the closest I can usually find is poplar. It's not as easy to work with as your garden variety weeping willow, but I can manage it with a bit of elbow grease. But for most bigger jobs in the Adirondacks, we just grab an axe or a hatchet. Nobody bothers with huge knives here. I don't think I've ever seen anybody here ever try to baton there way through a branch.
So not is this guy good with a small knife, but he knows exactly what woods to tackle with one.
I take the middle road most of the time. I carry my saw scout. The big spear does a great job. And if the spear isn't enough, I have a small wood saw.
