Combining escrima plus BJJ can be very, very valuable. I once taught a "how to bring a knife to a grapple fight" seminar on just these things. However, I have found that knowing one, and not the other, can often result in a very poor outcome.
Also, instead of shock knives, a cheap alternative is to use training knives coated in chalk. No sting, but you easily see who gets cut without a giant mess/need for new shirt afterwards.
Dealing with knives is mostly about core principles (bone shields, thumb-bed control, clearing the centerline, etc). Good, quality martial arts of any form can help provide a lot of the mechanics and timing, along with the follow-up techniques, needed to defend against a knife, once that additional set of principles is learned.

For personally self-defense I just need to go home safe. Killing, disarming, or subduing the opponent isn't required for me to "win" and I have the added luxury of being able to just run away I see the opportunity.

By using these two techniques I can control the arm and not lose it while I going for some sort of submission or strike. Of course we practice all newly designed techniques during sparring sessions to see what works and what does not. If any techniques that I can not pull off during sparring will not work in a real fight so we don't use anything that has not gone through trial and error.
