My mistake.
Looks like you ripped off that video from Funker Tactical.
They posted the video to YouTube last November.
Here’s the real, original link -

One word: Gun
After 10+ years of training in martial arts I can definitely say this video is crap. An aggressive guy on adrenaline with a knife would have taken him out.
The only effective strategy I’ve ever seen (and this one is not a great option) is to acknowledge you’re probably gonna get cut, and you control where you get cut. Its better to get a superficial wound than a fatal one. My instructor brought in a guy who does training on this specific drill. Extremely difficult stuff but it can be useful if you’re really proficient in it (no,I don’t claim to be proficient in it).
Get away as quickly as possible is still the best strategy.
I love that move but for me I think its wiser to take a gun to a knife fight. :-)
