that what i thought about the wire saws,you need the best and have to work slow.the last time i used one was in the 60's-Scouts--and not since then because it was such a hassle to get to work. the SAK saw is a wonder.i never had one untill my wife gave me a Farmer model for my birthday and since then i use it to cuts sticks for the dogs to chase and was surprised the first time i used it--it really works!..Sven makes a short model of their saw and i take it on canoe trips.it will buzz thru fire wood size sticks in no time and i have cut some good size dead fall from portage trails with it..now if someone made a SAK style and quality saw that was a bit bigger than the one that comes in the knife that would be a choice bit of gear.the folding pruning saws are close to that quality--has anyone looked at the saws from Japan?.they seem to have some that cut both ways.
