Video: Knife Defense Fundamentals by Glenn Murphy, Chief Instructor at NC Systema

This week at NC SYSTEMA, we slide back into the study of knife defense.

Knife defense videos are a popular target for Internet trolls, 'keyboard warriors', and so-called 'reality martial arts' enthusiasts.

"I would just shoot the guy"
"You should just run away"
"Great way to get cut"

These are all popular refrains on comment threads relating to knife videos. In some cases, these are valid criticisms. When faced with a knife-wielding attacker, deploying a firearm or running as fast and hard as you can are both perfectly valid responses.

Then again, they can also be pointless cop-outs that beg the following questions:

- What if you're not armed 24/7?
- What if your weapon jams?
- What if the attacker is too close, and stabs you before you can deploy it?

- What if you're injured, and you can't run?
- What if the attacker stands between you and the exit?
- What if you're carrying or defending a child?

I have yet to see a convincing answer to any of these questions from the would-be warriors and critics online.

Yes, you'll probably get cut. In all likelihood, you'll be hospitalized after the attempt. But in the situations above, that *might* just be preferable to shelling up, grappling ineffectively, or leaving your kids to die.

With that in mind, here we offer three basic principles of knife survival

1) if you can run, don't hesitate
2) fight the attacker, not the weapon
3) use leverage and/or your enivironment to your advantage

Comments and questions welcomed.

Video: Takedown Fundamentals

This week we're returning to basics at NC SYSTEMA, studying standing grabs, holds, locks and takedowns from simple to advanced, from applications to escapes and counterattacks.

It's good to study a variety of locking, wrestling, and throwing concepts - not least because they may be used against you. Skilled wrestlers and grapplers are not to be underestimated, and without sufficient experience in how to escape or control them, you may not get a chance to apply your favoured striking, kicking, or ground-fighting techniques.

That said, a few solid basics can go a long way. With proper timing and precision, you can extrapolate two or three key principles into hundreds of practical techniques. The key is training for efficiency, rather than racing toward the intended result.

Here, Instructors Glenn Murphy and Raymond Desmarais show three fundamental takedown patterns which can be varied and combined to create a wide range of subtle counterattacks.
