[K3CAL] Reward Offered

Sat Mar 16 13:42:24 EDT 2024

I have used this rope saw or something like it mostly successfully on tree
limbs high up. But I am not sure the chain teeth would cut another rope it
seems like they might get stuck or caught on the rope.  But I like the
concept. Maybe you could get some heavy weight braided fishing line over
the rope where you want to cut it and use friction to burn/cut through the
line.
