File or stone to sharpen machete

[FortyTwoBlades]

As others have mentioned, if you're gonna' have one sharpening tool for a machete, make it a file. But a scythe stone is a good further refinement, and can be brought to the tool in much the same manner as a file.

^That. The 110-grit Bull Thistle is a $12, great all-around stone for machetes, garden tools, etc. And also works for recurves.
