Machetes to me are in a whole different category to “big knives”. They are actually useful around the yard. I think of machetes generally having blades over 10”for serious yard work. Big knives up to 10-11” are more just for fun, or for when packing and portability are an issue.
The Condor 13” golok has been my best chopper, while the Baryonyx machete is effective against a wider range of smaller vegetation.
