Fair comments above; sawzall-type blades are slow cutters, but they do cut through most everything. When you're facing an unknown task, that is of value.

If I was expecting wood cutting, or other soft materials, I'd choose a bow saw or folding saw (pull-cut) blade. In fact, I often save weight in the bush by packing a smaller knife and a folding (wood) saw blade without its heavy handle. Wearing gloves, I can take down a six-inch tree faster than most guys with an axe.
