Just out of curiosity, how would the saw be useful? If push came to shove, anything I could cut with that saw I could break with my hands, across a knee, or in the crook of a tree. Or I could chop or baton it with my knife.
The BCB wire saw that comes with the kit is the
smaller and cheaper of the BCB saws. This particular model is ok as far as wire saws go and perform a little better then the regular run of the mill surivival saws found in mainstream retail stores
The BCB Command wire saw is a step from the saw that comes with the Ranger Rick kit. It is more beefier, is 28" long and has wrist attachments that aid in keeping your fingers from fatigue when using and pulling on the saw using the small O rings.
As with any wire saw, care must be taken not to bind and or kink the saw when cutting the wood and is easier said then done at times.
I personally prefer and carry a folding 6" serrated blade garden saw for any small wood cutting needs. It much more versitile and can be readily re-sharpened with a small fine file or whetstone.
Regardless of any downed wood cutting methods, generally if you can cut 1/3 to 1/2 way through the wood, a quick whack over a rock or suitable solid matter like a log will be enough to snap the wood on the cut line. This save wear on your saw, save wear on your arms and also save time when you have to cut enough wood for a fire of any reasonable duration.
