I would rather see this thread in "Tents-N-Trails" but I have to agree with Pappy..."IF" the wire saw he uses is being dicussed. The one originally brought up doesn't look all that great to me. I use a wire saw. I carry 2 small wooden dowels that just fit in the rings. It makes the operation much easier on me. Your hands/fingers do not get nearly as tired and not nearly as fast!
My favorite "go-to" tool is my little Swedish limb saw. (I think it's Swedish???). I'll try and dig it up this weekend and post a couple of shots.
