Hey Scafool,
I agree with what all the replies before me said. I usually use my Laplander saw, but the Pocket Chainsaw works well also, although it seems like more effort is required. It is a little a bit of a pain to have to keep looping the pocket chainsaw blade around the wood, then putting the wrist loops or toggles back on.
I have had reasonable luck with the 8 strand "commando" type wire saw but only on small material, cut very slowly. The cheaper wire saw that is a single strand of "barbed" wire broke on the first sapling; Junk.
I like having all 3 of these saw types (plus a few more) as I can find a purpose suited to each of them.
