One of my partners brought out a brand new Milwaukee 6" pruning chain saw, tell you what it made quick work on a couple elk we were lucky to harvest.
It was a M12 Electric version -

I have, and used the larger M18 Sawzall but it is heavier, (like two hands required) and unless you have the right blade for it the chainsaw beats it hands down.
