FLAT of my STRONG

Should sword blocks be done with the blade or the flat of the blade?
Can you block with the weak or must it be with the strong?

Parts of a sword

Some people make it very clear which way is correct:

He's doing unarmoured longsword, which means that you can use both hands' strength as part of the block.
When doing SCA florentine however we only have the strength of a single hand to block with. We have always been told to block with the blade and I think it is for this exact reason.

We will have to try out blocking with the flat of our strong, to determine if it is even possible with single handed swords.

In SCA heavy, we're assumed to be wearing chainmail; which means that light cuts are completely ignored. This means that to block a shot, you only have to take the force out of a blow. You don't have to prevent the blade touching you, only foul the shot. This means that a kind of weak block can be effective with the weak part of the blade.

So it may be possible that we'll end up make a video like the above one, but with us chanting "blade of my weak".
I somehow doubt it though.
