Can remember the make, but I found one of the smaller twisted wire saws a long time ago that was built well and worked great. To avoid the discomfort of use, I remember cutting some small branches into two sections that fit through the split rings to make full grip handles that worked very well. Since then, I've broke the last two I bought...they were pretty crappy. The Pocket Chain Saw works the best and that's what our helo pilots carried in their vests when I was down in South America.
I still prefer a folding saw...Silky, Kershaw/Bahco, Sawvivor, SAK.
