X11 or X7 would probably be a bit lighter and more durable. I know its ‘plastic’ but I’ve beat the shit out of mine for 15 years and it hasn’t loosened up at all. Wood handles get finicky in the elements. The Fiskar plastic handles are hollow, too, you might be able to pack a flint kit up in there for energency use.

Something like an Eastwing is goong to be a better chopper, but these will split better. Both are useful.
