This isn't one of the video I was referring to but this guy does what I have seen in the previous videos.

I found this guys site :

I also found this video FAQ :
Twirliing. Where to start? (* My background is in Balintawak and in Modern Arnis - I teach both in privates, seminar, and class format *)
1) Keep your hands closed or you will loose the weapon (* as stated in this video *) or it could be knocked out of your hand.
2) Attributes of the weapon. Understand the attributes of the weapon. Is it an impact weapon blocking an impact weapon or is it a blade tip heavy Machete, or some other blade that has different attributes. I will mostly comment on the Machete and Stick here.
3) At about 4 minutes in he is close to a twirl that is used in Both systems. At 9 minutes in he does the twirl. In this case look at the weapon as an impact stick. if you strike out a forehand and the opponent blocks and then pushes your stick down with his hand and then strikes back your stick is out of position. If you do the twirl from about 9 minutes in to the original video linked here, you can provide a force to force block. Note: You stick should be a 90 degree angle to your forearm when you are complete and the stick should be up and down straight for the systems I teach. This is not shown in the video.
This twirl enables the small "C" block we execute in Balintawak and the block without a brace in Modern Arnis.
If the opponent grabs the stick, (** I always get this question as well because it stops the twirl option **), you attempt the twirl, listen to the inanimate object and realize it is not going to execute. You left hand which is at the ready then reaches out and traps down form behind his weapon, and guide it down into your weapon. Of course now he has a hand on each of the weapons and so do you. There are techniques from here on both sides of course, as all techniques have a counter. This does require timing and skill so beginners like to grab as others who do not have the skill can get hit.
But what happens if I do not want to hit him in the arm or body and go for his head so he cannot trap it into his weapon? (* Yes I get this question as well *). This is even easier. Your left hand which is at the ready slips the opponents weapon as you bend your knees and go under the weapon.
** Yes you should see and feel this happen to truly understand **
Now, assume you have the blade tip heavy machete. You perform the same twirl to get your blade back up and no it chops into the opponents blade. Of course there are discussions about blocking with the edge versus the side. Search for that here and other sites as well. They are not going to grab the blade, (* if they are really good and pinch the flat of the blade and it is not an accident, BUY THEM A BEER, before they cut you head OFF *), only move it off line. Also this is where a Dagger in the left hand comes in, and can be used to deflect the blade and with a good cross guard keep tension on the opponents blade. Of course once again, most people do not have this training to listen to an inanimate object through an inanimate object. Some do train the technique without the listening, and can execute it though, so be aware.
4) At about 6 minutes a 5 seconds or so, he does the reverse figure 8, or as in Modern Arnis it is called Figure 8. This works with all kinds of blades. Those that are tip heave and chop or those that catch in the middle of the blade and draw cut. Note: the hand is always closed and your are twirling the weapon on both sides of the body.
This of course can be done with a stick as well, yet I find if you put a blade in the students hand for this they get the angles from the start to understand that tip placement and control is required.
I hope this has helped.
