The wire saw is a thin (1 mm), relatively short (approx. 50 cm) steel wire with sharp grooves and a ring at both ends.
With this saw, which is easy to carry in a pocket, thin branches can be cut. If you want to cut high branches, attach a rope to each ring. The saw can then be thrown around a branch. The ropes are pulled with one or two people.
