I saw the first couple segments and two things stood out. The first being the effectiveness of the tomahawk. The second was the use of multiple knives as presented.
I was not surprised at all with damage done when Snake struck the stationary skull with the Tomahawk. It was devastating to say the least but what was interesting was it seemed Snake himself was surprised at the damage. This could come down to editing or something but I found it interesting, curious. If Snake would have stayed with the Tomahawk and focused on that, it would have kept my attention. I'm also very interested in Native war clubs and things too.
The second thing that stands out is the claim that Native Americans would carry multiple blade weapons and tend to throw them and use them in similar fashion as advocated by Sayoc Kali. I am no fan of Sayoc and believe they lost the plot in modern training crossing from training based on facts into training based on comic book illustrators personal fantasies of what knife combat should look like.
I have personally viewed hundreds and hundreds of pictures of Native Americans. I have been all over the west, been to countless museums and even spent time at the Smithsonian Institute, University of Oklahoma, and other libraries looking at Native Artifacts. I have never seen one picture of any Indian with multiple knives much less found any evidence that any Indian Apache or otherwise would carry multiple knives. Certainly there could be a argument made that one would carry a large and small knife but that's where it ends.
When I first came across references to Apache Knife Fighting a few years back all kinds of red flags went off. Later when I found the leader of the organization was from my home state of Arkansas I decided to look into the subject in depth. My conclusion was it was one guys money maker and there was no historical evidence to back up any of his teachings. Later he would be imprisoned there was then criminal evidence against the man but most already know that story.
I would like to point out a few things here, The first being that steel knives were a western deal. All steel knives used by Indians were obtained outside of their population and were made by others. Native Americans never had any history of smelting steel for weapons and even today outside of a few farriers they have no representation in knife making or manufacture.
Apache were a product of their environment. They were hard and tuff from living outdoors year around, it does not make any sense for them to carry more than one or two stone knives as they could make more if needed and steel knives were a great expense.
Then there are traveling and safety issues that make such ideas highly improbable. While on active duty I was known to carry all kinds of extra junk around but later when I went backpacking for a entire year, I learned the value of weight. I cannot imagine any right minded person ever needing or wanting to carry more than two knives. Two guns? That is a separate matter because of ammo issues.
If anyone can come up with anything as evidence to show that Apache Knife Fighting as currently instructed is anything other than a made up story I would like to see it. I would also like to see the pictures of any Native American wearing the Sayoc Rig either afoot or on horseback.
