That is indeed a very good saw for its size. I have one too. Haven´t used very much but enough to have got a feel for it. Plus it is practical for backpacking because its foldable. And the teflon on the blade makes it glide nicely through fresh wood.
You don´t cut down huge trees with it but up to a diameter of some 6 inches is doable.

Don´t remember if I have posted this before so here is my "bushcraftset".
Doesn´t weigh much, around 1kg and doesn´t take up much space.
But get´s the job done building a shelter or fire.
