I beg to disagree, but the engineer in me rebels at your refusal of point 1
I understand and agree that the impact energy is the same, being the two blows delivered by the same arm after all, however the impact of the thinner blade is a) more elastic, which dissipates more energy through deformation, and b) spread on a larger area, again due to deformation, lessening the pressure on the point of impact. This means that an impact from a heavy blade is inherently more dangerous than from a midgrade.
I understand that if you are well protected you will not get hurt seriously, and I do appreciate the emphasis on this, but remember that the energy you are hit with still has got to go somewhere, and I see no advantage in using a more dangerous blade when there is no need at all; also, if you get hit somewhere you don't have armor on, there is less of a chance of damage.
Just ask yourself, if you had to be shot with a bullet in training, would you rather be hit by a soft rubber bullet or a hard rubber bullet? To me saying that they are the same makes no sense at all.
I didn't say they were the same I said the mid grade blades are just as dangerous as the heavy grade blades. I can do the same damage with both. If you can take a full hit to the body with a mid grade, I may entertain the idea. But the difference in getting hit with the mid grade vs the heavy grade is minimal.
Midgrade blade provide ZERO safety and should not be treated as a safety measure.
Stabbing, as I discussed earlier, is illegal here, and I believe there is a very good reason for that, armor or not armor: stabbing concentrates the energy of the blow on a very small area, and is extremely dangerous due to that, as unless your protection is rigid, you will get hurt.
You make my point for me.
Illeagal or not, you will get stabbed. the accidental stabs are the ones that you worry about. A stab to an armored area does nothing. But to an unprotected area it is very dangerous. Simply telling people they can't stab is no reason not to protect against it.
Again, cups are compulsory here... You know, it's funny if you think about it: we Italians protect our family jewels more than our face, and it's the contrary for you guys... Not making fun of you, just a funny thought.
we do wear cups and groin protection. And it's not the face you should worry about. It's the head.
I hope it all didn't come out as a useless polemic and rebuttal of what you are saying, if so I apologize in advance, but I just couldn't agree with the first point... I can't see any reason for using the heavy grades, as you can always replace a blade if it gets damaged, whereas it's harder to heal a broken arm.
Look at the flex from a full force shot tot he hands in the video. All that flex from the heavy grade blade. All the energy dissipating out, just as you say. May not quite as much as a mid grade, but way more than is necessary to to prevent breaking an arm. You will not be able to break bones. These is not the injuries we are talking about. To the joints and the fingers are the most at risk. You might be able to fracture a finger, but if you wear good gloves you won't have worry about it. It still stings but no harm done. Both mid grade and heavy grade could cause hard to the skull, but more importantly, there is a hilt attached to that blade that can lacerate, puncture, or crack your noggin.
If you don't want to use heavy grade that's fine, but don't fool yourself to think that the risk of injury is less with mid grade .
WEAR GEAR! Full contact should be full gear. Head to toe.
Jogo Du Pau has Great armor!
Thanks for listening!
Ditto.
