I know it gets confusing. One company's panga looks like another's barong, looks like another's bolo. I just call them all choppers.
Some are called Pangas, which is what Africans call a machete.

Some are called bolos or bolo machetes, after a large knife used in the Phillipines.

What the heck is this one? Becker calls it a "Patrol Machete". It looks like some goloks I've seen but more like a cross between a kukri and a bolo.

Then there is the Barong, a tool/fighting knife used in Indonesia.

And one of my favorites, a kukri/bowie hybrid Cold Steel called the MTC or mini terrain chopper.

And there are the more familiar latin style machetes that most Americans use.
I have used all these and more, and my choice is the DFLE Bowie for my next swamp trip. Done.
