That defeats the purpose of a machete. Machete blades are thin and made to slice foilage with a swing. Serrations would need a thicker blade making it a chopper and the serrations would catch on every cut. What you are talking about is a saw with one handle and they tend to work poorly. If you need a machete, get one without serrations. If you need a chopper get a Busse or something simmilar. If you need a saw, get a saw. Try and force all 3 things into one and you get a tom brown tracker... ugly, impractical and outpreformed by a knife, saw and machete. This is the reason they dont make serrated machetes and if a company does stay far away from them.
