One thing that you have to keep in mind when your trying any disarms is not just worrying about the mistakes that you might make when attempting a disarm but, for every disarm there is a disarm counter. In sayoc Kali we have a whole bunch of disarms, which are probably very similar to all of the disarms that are being discussed here. The usuals forearm strips, high line, low line & percussions. The problem is that our disarm counters are alot more effective then the disarms & they are designed not only to stop the disarm but, the counter usually results in a very serious vital target injury & there is nothing that the person attempting the disarm can really do to stop it, it happens to fast & it usualy results in some type of major artery damage because the counter isn't designed to only stop the disarm but, to eliminate the threat by attacking a vital target on the half beat. So if you commit to a disarm, the disarm counter is like taking candy from a baby. So my advice is if you do attempt a disarm be ready to bail out & at the very least protect your vital targets even if it means taking a less serious cut. I would much rather projectile somthing , run or draw a blade before I would attempt a disarm. Although I practice disarms all of the time in training & I am actually pretty good at them but they are just to risky if somone knows some nasty counters.
