I've held both an AK and M43 side by side and they are completely different animals. The AK is a brute. The M43 is elegant. The AK is a long axe. The M43 is thick, curved, tough machette. The width of the belly of the blade helps create this effect.
Personally what I'd really like to see is a side-by-side test of an M43 and the new Foxy Folly's. Seem to be in a similar category. Anybody up for it?
