If you want a pocket-saw to take care of small branches - that would do the trick. The price is comfortable.
Personally - I prefer having a bow-saw with a few spare saw-blades like the one pictured below (just some random picture I snagged off the net). My bow-saw has easily sliced-n-diced 6x6 posts, small trees, etc.
Bob - when I was still a wee-one, my dad had that same style of saw that we took with us when we bush-wacked cross-country skiied (vs trail-running). We used that kind of saw many (MANY) times. My dad even sew'd up a vinyl casing for it to keep it wrapped up and together when strapped to the side of the pack. (My dad used to own / operate a vinyl repair business fixing car seats, house and office chairs, sofa's, etc).
What's funny is I have one of each !! but I don't have the one that I asked about, was thinking for my BOB... nothing screams "PEOPLE" like the sound of an ax chopping wood..IF your in hide mode, of course if ya are a fire may not be the best idea..
This little saw would handle what we call Squaw wood real easy ...
