I had this banana tree to cut in the garden :
The main tree (hidden behind on the picture) is 3 meters high, for a trunk diameter of 20 cm at 1 meter height.
Banana trees are for those that never encountered one structurally like rolled cardboard, filled with water. They produce a kind of gum, which get very sticky and stops penetration. But the penetration of a big blade in a 20cm diameter is impressive. They make a good test to check how blades penetrate in wood, as the length of the penetration is bigger, and thus can be measured.
You can see here the Survival Golok, the Baiwan, the Locka, from top to bottom
A different view
The deeper penetration is the Survival G. The baiwan did not enter at same angle, so I retested it later, with the same angle, it is second, The Locka glanced, and would be last, but not by much. Actually, the lock again shows it is a contender, because, though I had little space for movements, I could accelerate it more, and therefore get a similar result.
I could not add another blade on the tree without crossing blades, which if I remember well "ghost busters" could cause the end of the world, so I then removed them and tested the Borneo Parang. I have no picture, but the Parang does slightly better than the Survival. 
No blade went though, but I expected this, as I chose the tree this way. 70 kg falling on you while holding a big blade is no fun.
A bit more fun : the Baiwan and huge leaves
The place cleaned
The blades are back in the backpack, the leaves in the front I’ll use tonight for cooking my chicken curry, eh eh ! They are typically of use to survivors like you guys. The core of the tree can be eaten, and is just a bit more fibrous than palm-tree core, but less tasty.
The cut-up trunk and card board structure
The cleaned place
The compost heap
The trunk has been dispatched in little pieces. The Borneo Parang was the only one that could slice totally though the whole diameter of the trunk, the SG was just behind, and needed a bit more swing.
So the order is :
Curiously, this follows the centre of gravity repartition of the different blades, thus confirming what everybody knew, a good chopper has weight in the front, the axe is indeed a very good tool for chopping ;-) Seriously, an axe or hatchet would not have allowed me to dispatch this tree in 1/2 an hour.
Still, check the pictures, differences are minimal ( I also base my classification on the later dispatching on the compost heap)
Well the fun took me 1/2 hour, the cleaning of the blades another 1/2 because this bloody gum had stuck to them. the kitchen cleaner and scratch pad could not get rid of it, and I had to resort to citrus solvent, as I did not have alcohol...
Needless to say, no blade was damaged, I do not see how they could in such a tree :-)
The blades involved Borneo Parang, Baiwan, Loka, Survival Golok M, Hitam 
Please read this safety warning, if you intent to use such blades.
 I got excited and felt compelled to take the tree down at that moment, which is why there is no picture
 again Wandi amazes me with a handle design about which I doubted at first
