Red: take up hunting.
Highly reccomended: tape or otherwise attach a smaller sheath with a 10-inch or so medium cut mill bastard file to your machete sheath to keep the edge maintained. And add a pair of work gloves- leather or cotton depending on your local climate, for wear when yiou'tre working with the brush cutter.
A guy whacking away with amachete can be heard for well over a mile when the conditions are right [or wrong, depending on your point of view) though tghat does not lessen the usefulness of the tool when it's needed; it's just another consideration worth keeping in mind.
And is also a good reason why a good bowsaw is a worthy addition to your list of useful pioneer tools. Which is actually a good suggestion for another list/thread.
One of the reasons to have two knives, like a machete and a folder, is because you can use one of them as a hone for the other. You’ll need to maintain the blades daily because a hone won’t affect a rounded edge, but the knives will stay sharp if the hone is used for maintenance. Besides that, plenty of natural and artificial stones can serve as sharpeners.
