No. You obviously don't know what you are talking about and have never really trained weapons. Swordsman do something similar to this all the time. FMA guys training with long blades do something similar to this all the time. You can even so something similar to this with Wing Chun Butterfly knives. So I really don't think you have "trained in a lot of weapons" if you think "you would never get close enough." Because you have to get at least this close to even land a strike! Unless you are throwing your weapon at the opponent!
Again, because I showed this in an instructional format where we are standing relatively stationary, you seem to have concluded that I would just be standing there waiting to do the technique. This is not true. Like I have already pointed out...things like this are done when the opportunity presents itself. You are moving around dynamically adjusting distance/range, and when the distance is right as your opponent tries to land a sudden thrust or backhand strike you meet it with the side parry....which is really essentially the same thing as a backhand backcut. So ideally you would be cutting his forearm or hand as you keep his strike from landing. And you would typically be angling out of the way as you do so. If you are far enough out that you can't easily reach his forearm or hand, then you end up with blade on blade contact.....which, when you have a 10 inch blade on a Bowie knife, is not at all unreasonable or difficult to do. A big Bowie Knife is essentially a short sword.
And if you think you can always stay at a distance during a real fight with weapons and will never end up closing with the opponent...again, you obviously haven't done much serious weapons training!
And I will also point out that the side parry is a pretty basic and instinctive response. Give a beginner a stick and throw a blow at him. If his hands are down and the stick is to the left of his center, he will very likely do an outward sweeping motion to try and keep from getting hit.
So really, to come here and see people questioning the utility of this very basic and instinctive motion makes me really question the knowledge and experience of weapons of the people doing the questioning. No offense intended. It just kind of surprises me.
Hey man no need to get salty. I actually like a lot of the stuff you do.
The thing is, a healthy dose of skepticism is required of those that don't want to fall into the bullshido trap. So yes, when I see things that look to be a little suspect(such as playing Errol Flynn at close range with short blades), I might require a little evidence before swallowing it whole, especially when it runs contrary to what my own experience tells me.
You used the example of Dan inosanto/escrima. Have you ever heard of Dog Brothers? They do full contact fma stuff and its pretty brutal and visceral stuff. They get hit constantly and quickly, and it's all pretty much a blur. There's very little parrying, and the rounds are fast..and these are dudes that actually train at speed for competition.
And it's much easier to block with two sticks as long as your arm than it is to block with a single blade less than half that length, against an blade that's also less than half the size of a stick, coming on a much tighter arc or thrust.
Are you really that fast? I'm sure not.
I would say if you can actually get close enough where he can stab you or slash you and you aren't filling that entry with an attack, or initiating a grappling situation to gain control of his weapon,or if you do not remove yourself from distance upon completion of said attacking entry(either way, where you need to be to execute any many of the knife counters you show in your videos), your odds are not good of stopping the next one.
This is no insult to your skill but a matter of physiology and human reflexes. The guy attacking already knows where and when, you do not. Sure, you might stop some of them, but then again you may not. The odds are certainly against you.
On another note you do realize that creating a syllabus of moves does not make that syllabus of moves effective automatically right? Only intensive pressure testing can do that.
Why not get some prop knives, a partner and some dude to act as the kill ref and make a video or two of you actually pulling some of this stuff off? I guarantee at least one of us will be surprised by the results.
As for the weapons training I've never done(since you chose to shift the discussion from the efficacy of technique to me personally, aka argumentum ad hominem), I didn't do 4 years of Arnis concurrent to my WingChun training(where we certainly didn't spar on Friday with our padded butterfly swords), I didn't study fencing with an ex Olympic alternate for two summers, and I certainly don't spar in class with the rubber knives from the rubber weapon crate a couple times a week.
That's not to mention all the personal training I've never done on my own throughout my life with my extensive weapons collection I don't have.
When you're right you're right I guess. What else do you know about me personally through intuition I wonder.
