Knife Attack and Defence Myths (Videos)

Found these two videos over at the senshido forum.

Warning: These videos contain graphic images showing real knife attacks for educational purposes only.

and this one,

Overall, I like the message the producer of the videos is trying to make. There is a LOT of garbage out there regarding knife and edged weapons defence. I am not so sure about one or two of his points but overall, I found the videos to be very interesting and thought provoking.

What are your thoughts?
