MBC/CBC student perspective
I've trained with Mr. Janich and I have to say that I think his system is well thought through and the training methodology is very good for training reflexive responses to certain types of attacks. He teaches what is essentially a Filipino knife style that has been modified and trimmed down a bit to work better for American sized people working in a civilian context. The targeting is designed to disable the attacker - killing them isn't the primary goal of this style. That said, when you're playing with knives, the targets that can disable people are often pretty close to the targets that can kill them (ie flexor tendons in the forearm are right next a major artery).

Once students can do that then they start what is referred to as "the chess game" where there really is no pattern and anything could from any pattern could be thrown in at any time.
There is little or no knife sparring in MBC. I think the idea is that if you are getting into mano a mano knife fights then you're doing something wrong. There is, however, quite a bit of work done with learning how to deploy the knife under pressure during an attack.
Additionally, Mr. Janich teaches a Counter Blade Concepts course that focuses on dealing with an knife wielding attacker empty handed. I don't have as much experience with that system but from what I've seen/done it seems like a pretty solid way not to get stabbed in the vital parts. I'm not yet convinced of the methods for controlling the weapon and disarming the opponent but I haven't given it enough practice to really be able to judge.
