I mean, there are only two long blade weapons I know of, Machete and the even less common Katana. I mean, The Machete tends to be my mvp as far as weapons go if I can ever get my hands on one, and I would imagine The Katana is just as good if not better.
I guess the problem there is that Long Blades need more chances to spawn, I mean, with abundant everything, it's not uncommon for me to be able to be drowning in Fire Axes and Wood Axes, but only be able to get 1 or 2 Machetes.
