Definitely Cacoy's "Eskrido." Cacoy has formed his own organization called the
Cacoy Doce Pares International Federation. You'll see in the circular section on the top left of the home page that several of the pictures show various throws and locks. It should be said that most of techniques in Eskrido involve using the stick as a lever to effect locks and throws - but there is an empty hand curriculum as well that is quite comprehensive. Although Cacoy has written two books detailing his art, there are also two excellent DVD sets by one of his students, Chris Petrilli, that show several hours' worth of locks and throws that follow Aikido and Silat principles. Obviously Doce Pares Multi-Style still contains the extensive Eskrido curriculum develeped by Cacoy, and San Miguel Eskrima has it's own locks, tie-ups, and throws using espada y daga.
There are many Filipino martial arts that have a "lock, tie-up, throw" curriculum that includes both the use of the weapon and with the empty hands (Pekiti Tirsia Kali and Modern Arnis come immediately to mind). In this respect I think that they are no different from any other weapons-based martial art: there is a place, albeit a small place, where this kind of technique is important and appropriate, and people choose to become expert at it or not depending on the amount of time they have because it is very, very difficult to pull off. In this regard it is a little like disarms: not the most important aspect of your art but it has its place. And like disarms, it can be done effectively and routinely by certain people (my teacher saw Cacoy disarm a very good, non-compliant eskrimador three times in succession during a sparring match - and he did it effortlessly).
There are several Filipino martial arts that have a "Combat Judo" curriculum that generally involves empty-hand vs. knifes, but it doesn't look anything like Japanese budo arts. They are generally defenses against broad committed attacks by someone relatively unskilled with a knife (99% of the population). San Miguel Eskrima teaches several techniques in this regard and has a two-man from wherein there is a series of attacks and defenses involving stops, locks, and throws. The term "combat judo" is probably from the Second World War.
