I humbly suggest the Ontario 10” machete.
Chop and baton to your heart’s content. Sharpen with a file (or rock in a RLSS).
While not stainless, the parkarized finish provides adequate protection. And one can always hit it with some spray paint for additional protection.
Cardboard and duct tape can make a decent storage sheath (and source for duct tape in that RLSS).
When I first got mine I was all fussy about the polished edge and edge holding. But soon realized that the slightly softer 1095 responds well to a couple swipes with a file, which takes no time at all.
And it’s not like one is leaving a couple hundred dollar investment in the truck tailgate for a just in case scenario.
