Hi Jay,
You said
Stu: I would answer your question with a question. Why do the fechtbuchen not show parries in unarmed defense against the dagger? Why is the initial move always a grab to secure the weapon arm before any countermove?
Which is a very good question indeed.
Since I will presenting on this very topic in October at the Australian Fencing Conference, I have been doing some pretty hardcore testing and a whole bunch of research.
The short answer is that it is down to a difference between medieval daggers and footwork and modern daggers and footwork.
I'll give you guys the short answer and then extrapolate if you need me to.
The first reason why is that medieval daggers are longer than your forearm. If you block a downward thrust with your left forearm then you may be hit in the face anyway if you don't get the angle exactly right. This is one reason why when defending with the left hand, a grab is better than a parry. In addition, because of the passing footwork found in medieval martial arts, an undercut is possible even with a dagger. If I am in distance to bear a blow on my left forearm then my attacker can fall under it during his strike and hit me in the side. If I make for a stiff armed grab then even if I miss I am out of distance for this falling under.
The same thing doesn't quite apply to right arm parries which can work well, especially against hard attacks. If someone stabs from above and I move to the left in order to bear the blow on my right arm then then the chance of being "fallen under" is reduced as this is difficult for the attacker to do on his left.(Almost impossible if you trap his wrist with a dagger hook of your own). (Of course when armed in forward grip you just single time them in the face as you parry)
OK now we skip forwards to modern methods. These methods do not often involve passing steps which cuts down the angles of attack that can be used dramatically. Because the weapon often starts close to the centreline, tracking it to grab it is often difficult which is why arm parries are most often used. Most modern daggers are not long enough to hit the face even if the left arm is bent at 90% for a parry. As such moves like X blocks and full arm parries are the best way to deal as
you can move late enough in the action not to be tricked by a killing thrust that turns into a harrasing cut. This is what people don't get about the proper execution of the X block btw. It isn't passive, it's active. Do it in the Karate fashion and you may well have your forearms cut to ribbons. Anyway, the proper execution: The forearms are shot out at the last possible moment to impact as strongly as possible on the incoming knife arm. If facing a right hander, the right arm is extended slightly further than the left in order to get to the outside of the attacker. If possible, a movement off the line to the left should be incorporated although this method works without it.
Does this cover things Jay?
Cheers,
Stu.
