dd,

Don't know the brand name.  I got mine off a military surplus site. It has round finger rings on each end and in pinch could be used as a small game snare. I believe it's a standard issued item in pilot's ditch bags.

I found that by taking a suitable sized branch, notching each end, and attaching via the rings, you would get a serviceable bow saw.

Not for daily use, but more than adequate in a pinch.
