Cxt,

I fence saber and the "old school" moulinets, a cut needed for effective use of a real saber in real combat, have pretty much disappered.
They are not needed for Olympic style competition.

The fingers and to a lesser extent the wrist do much of the work now.
And they allow bladework that would be nearly impossible with anything other than a "competition blade."


I certainly have nothing against moulinets/molinelli from the elbow, but it should still be pointed out that effective cuts can indeed be launched from the wrist. This was the preferred method of cutting in 16th/17th century rapier fencing, and it was even used judiciously in 18th century Anglo-Scottish broadsword & backsword-play. Several period fencing masters mention this.

FWIW.

Peace,

A_M_P
