Wire saws date from W W 2 british escape kits and were sewn concealed into uniforms. As such, they were meant to quietly cut through seasoned wood in barracks, fences, box car floors etc. A half century of experience has produced the best unit by BCB. The USAF saw works well, but is problematical with bulky turnbuckle handles, shorter blade length and simple availability. What exactly are we going to use a wire saw for? Producing small kindling may be done by hand and snpping to length. They are usefull as bone saws for disarticulating the grizz we shot with the AR 7 ( conversely, surgical bone saws are wretched for wood cutting.) Cutting larger firewood, lodgepoles,thrusting spears etc can be done with care and patience if a nicely finished end is required. If you can accomplish or delete any of these activities, you can just as well delete a wire saw.
