Yeah, I just don't like the biomechanics of folding saws, and I find that any deadfall (we don't burn greenwood in campfires) small enough for a saw can either be limbed with a stomp or snapped in a nearby tree's crotch, broken over my knee, etc. rather than sawn.
Anything too big for that will want a bigger saw or an axe.
If you look at the usage position of the folding saws, you'll note that it puts your wrist in contraction for use, negating the use of all those muscles in your forearm meant to stabilize the wrist/hand. You get some of them, but not all. And you don't get the benefit of the activation of larger muscles in your back and your biceps.
With a bow-saw, you get a lot of biomechanical efficiency when you cut that's less fatiguing and more powerful on the up and back strokes.
This is why I prefer a bow-saw/hatchet combo if I'm going to a place where I need winter fire or there's a lot of deadfall and I have tenderfeet along who want a big fire for marshmallows.
But that's why they make fords and chevies.
(I'm a physiologist, so that's why I think about weird stuff like this.)
