Machete Legitimus Collins & Co, Guatemala. Dunno if they're still in business but when I was cutting survey line (30 years ago) that was the best.

Machete and Blue Cross.

They go together.

PS A large machete is less work because it's weight carries it through stuff with less ricochet from unseen vines and limbs--how most people get cut. If you have serious brush work, get a Kaiser Blade, too.
