I have a 18 volt Makita reciprocating saw it wood be great for cutting a few bits of firewood to heat your shower water in a fire drum or cook a feed in the oz pig or something like that, and nice and quite too, it would handle 10cm hardwood no worries with a new blade, I take my full set of 18 volt power tools when I go away with mates camping up north, I charge them with a small $70 12 to 240volt inverter, It mite even be legal in a NP where chain saws are not, Craig
