Butchers usually use a knife for processing meat, then use a larger knife , or a cleaver, to chop bones. That is what made me think : if a cleaver can chop bones , why not wood ?

A saw is lighter off course, but it is a single-use tool. A hatchet, or anything heavy like a cleaver in this case, may be used for more scenarios. But I agree with most here that a cleaver's head weight is spread thin, and does not have the versatility of a hatchet. For example, you can use the other side of a hatchet head as a hammer. A cleaver is too thin for such a job. And it can't be used as a micro-shovel because it is not balanced that way, plus it is mostly associated with food, so if you use it to dig a toilet hole, then you have to toss it away or toss the food away!

About the swabs , seems I have to keep both, just in case.
