I have a pocket chain saw, a wire saw, and a 15" hand saw. the pocket chain saw is lighter and cuts tree limbs faster than the 15" hand saw. The cut are not like a band saw, but it will saw a tree limb in half in a few minutes with less work than anyother manualy operated type saw. I have used the pocket chain saw during camping trips to cut fallen tree limbs for the campfire. The best part of the saw is that is can easily cut through any size of tree or limb. The pocket chain saw is in my BOB, while the wire saw is in the PSK vest.
