In ARMA we train and spar with wooden wasters as well as steel blunt swords, with and without armor, but definitely with full intent. We rarely have serious injuries, though some bruises and minor bloodletting are just part of the fun.
A 3-weapon mask is required. Lacrosse gloves, or similar, are optional. That’s pretty much it for equipment. Intensity needs to rise and match the fighter’s training and control, but it can definitely be done at full intent.
Full intent?
no armor?
real steel unsharpened hand and a half?
you are full of it if you expect anyone to believe that.
