I've seen thousands of escrima, arnis and kali videos. The best videos that I have seen that deal with knife attacks are from the Dog Brothers. It looks like they may have updated their videos since I purchased DVDs. I'll have to watch the new content soon, but this is the material if you have to deal with a knife attack.
Everyone should watch these videos. Especially those in the military security or police force.
