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?
