I've seen flexible "wire" saws that can bend a good bit. These wire
saws have a grit coating. I need to cut down a tree and was wondering
if anyone has ever used something like this on a rope. You tie ropes
to either end of a "wire" saw, toss one end over a branch and pull
back and forth on the ropes to cut the limb.

I need to take down some high branches and don't have the $$$$ to pay
anyone. Don't mind climbing up high, but sawing/working up high is
another thing. I get spooked fast.

The branches are way beyond the reach of any poll saws I've ever seen.

Thanks
